  5. 64. Report on the AGATA experiment number 23.08 (Coulomb excitation of 60Ni)
    Agata Krzysiek (University of Warsaw)
    15/09/2025 14:10

    The nickel isotopes offer a unique laboratory to investigate shape evolution in the vicinity of doubly-magic N=Z nucleus, $^{56}$Ni (Z=N=28), which should exhibit similar structural properties to those observed in the Z=N=20 region. Indeed, observation of the SD structures was reported also in $^{56}$Ni, explained as the result of $mp-mh$ excitations like in the case of $^{40}$Ca. However,...

    Nirupama Sensharma (Argonne National Laboratory)
    15/09/2025 14:30

    We report on the current status of the Coulomb excitation experiment on $^{82}$Se performed at INFN-LNL using the AGATA array and the SPIDER particle detector. The experiment aimed to investigate the low-lying nuclear structure of $^{82}$Se through safe Coulomb excitation. Preliminary analysis of the online data has provided encouraging results, including clear identification of key...

  7. 75. (online) Report on the AGATA experiment number 23.054
    Naomi Marchini (Infn-Florence section)
    15/09/2025 14:50

    Experiment 23.054 was proposed to clarify the possible shape coexistence in the nucleus 106Pd. Around the Z=50 shell closure, shape coexistence has been firmly established in several isotopic chains, particularly in the tin and cadmium isotopes. Intruder states have also been identified in the palladium isotopes. Nevertheless, the coexistence of different shapes has not yet been unambiguously...

  8. 76. LNL AGATA Exp 24.01: Development of a self-calibration technique for gamma-ray tracking arrays
    Stefanos Paschalis (University of York)
    15/09/2025 15:10

    The performance of γ-ray tracking with AGATA critically depends on the accuracy of Pulse-Shape Analysis (PSA), which in turn is governed by the fidelity of the signal basis describing detector response. The currently employed AGATA Data Library (ADL) basis is derived from simulations, and its limitations are widely recognized as a key factor constraining the achievable position resolution. To...

  9. 66. Report on the AGATA experiment number 034 (23.049)
    Julgen Pellumaj (University of Padova, INFN-Padova)
    15/09/2025 15:30

    The $^{12}$C + $^{16}$O reaction plays a particularly important role in both the carbon and oxygen-burning phases of stars. Fang et al. measured this reaction in a thick-target experiment a few years ago, with both singles and particle-γ coincidence techniques down to a few nanobarns. However, the lowest energy points suffer from large experimental uncertainties which prevent discriminating...

    Jakub Skowronski
    16/09/2025 09:00

    The lifetime of the 6.793 MeV subthreshold state in 15O plays a central role in constraining the astrophysical S-factor of the 14N(p,γ)15O reaction, the slowest process in the CNO cycle. This state has long been the source of large uncertainties in extrapolations to stellar energies, and previous lifetime measurements were unable to resolve the problem due to limited sensitivity. The...

  12. 61. Lifetime measurements for the study of intruder states towards the island of inversion along the N = 20 shell closure
    Raquel Nicolás Del Álamo (INFN Padova and Università degli studi di Padova)
    16/09/2025 09:20

    Lifetime measurements are commonly used to unravel the nature and properties of nuclear states, as they are closely related to transition probabilities, which provide information on the nuclear wave functions. The experiment presented here aimed to study the interplay of spherical (0 ℏω) and intruder (2 ℏω) configurations in the low-lying states of isotopes on the edge of the N=20 island of...

  13. 60. Report on 238U(22Ne, x) and 238U(26Mg, x) to approach the Island of Inversion at N=20
    Floris Drent (GSI)
    16/09/2025 09:40

    In this presentation, we report on our current status of the analysis and preliminary results of two AGATA-PRISMA experiments performed at Laboratori Nazionali di Legnaro, consisting of a $^{22}$Ne and $^{26}$Mg beam emitted upon an $^{238}$U target. AGATA is coupled with mass spectrometer PRISMA for ion identification and γ-ray coincidence. In both experiments, the $^{238}$U target is backed...

  14. 70. Excited States Lifetime measurements in neutron-rich Ca, Ar isotopes
    Giuseppe Andreetta (INFN e Laboratori Nazionali di Legnaro)
    16/09/2025 10:00

    The region around doubly magic $^{48}$Ca is a cornerstone of our understanding of nuclear structure, characterized by the appearance of subshell closures at N=32 and 34 [1], and by the gradual disappearance of N=28 shell closure below Z=20 [2]. However, several experimental findings have challenged this understanding. Large charge and matter radii were found in $^{51-53}$Ca [3,4], showing...

  15. 67. Report on the experiment 22.101: Nuclear structure studies of neutron-rich isotopes in the vicinity of Z=28 and N=40
    RUTH MICAELA ILLICACHI GUAMAN (IFIC-CSIC-UV)
    16/09/2025 10:20

    The experiment 22.101 is a joint experiment to address four different physics cases devoted to studying the physics of the $\nu g_{9/2}$ beyond $N = 40$. These are aimed at investigating:
    • Collectivity and seniority conservation in the $\nu g_{9/2}$ orbital
    • Shape coexistence and octupole vibrations in $^{68}$Ni
    • Island of inversion and the role of intruders at $N ∼ 40$

    For these...

  16. 71. (online) Shape coexistence in $^{52}$Cr: lifetime measurement of the 0$_2^+$ and the 4$_1^+$ states
    Sara Pigliapoco (UniPD and INFN-PD)
    16/09/2025 10:40

    Coexistence between spherical and deformed shapes is largely found in and near semi-magic or doubly-magic nuclei.
    The region between the doubly-magic $^{48}$Ca and $^{56}$Ni nuclei is predicted to present phenomena of shape coexistence, although experimental information on E0 and E2 transition strengths connecting deformed and spherical configurations remains rather limited. In $^{52}$Cr...

  17. 63. Report on the AGATA experiment number 039 (24.011)
    Julgen Pellumaj (University of Padova, INFN-Padova)
    16/09/2025 11:20

    The appearance of a subshell closure in $^{56}$Cr (N=32) is confirmed by high excitation energy of the 2$^{+}_{1}$ state and reduced B(E2;2$^{+}_{1}\rightarrow$0$^{+}_{1}$) but shell model calculations do not reproduce the drop of collectivity at N=32.
    The discrepancy between the experimental data and the theoretical calculations for $^{56}$Cr may be as a result of coexisting shapes in this...

  18. 72. DSAM of 56Ni and 60Zn
    Matus Balogh (INFN LNL)
    16/09/2025 11:40

    In this contribution, we will present the current state of the analysis of experiments 23.07 and 23.09 studying the $^{56}$Ni and $^{60}$Zn isotopes. The goal of these experiments is to investigate the N=Z region by measuring lifetimes using the DSAM technique. These experiments were performed back-to-back, using an identical 16O@80 MeV beam and an identical AGATA+OSCAR (dE-E telescope) setup....

  19. 65. Pathway to nuclear structure in heavy neutron rich nuclei in the vicinity of N=126 and nuclei northwest of $^{132}\text{Sn}$ via multinucleon transfer reactions
    Rainer Abels (University of Cologne)
    16/09/2025 12:00

    Multinucleon transfer (MNT) reactions provide a powerful approach to access exotic neutron-rich nuclei. Excited reaction products have been measured in $^{136}\text{Xe}$ + $^{208}\text{Pb}$ at 1 GeV with the high-resolution $\gamma$-ray tracking array AGATA coupled to the mass spectrometer PRISMA at LNL (INFN, Italy) positioned at the grazing angle. For the beam-like fragments, energy E,...

  20. 74. (online) Report on the AGATA experiment 009
    Filippo Angelini (INFN-LNL and University of Padova)
    16/09/2025 12:20

    In December 2022, an experiment was performed at INFN-LNL with a $^{208}$Pb beam at 1300 MeV impinging on a $^{9}$Be target, using the inverse kinematics fusion-fission reaction for both nuclear structure and reactions studies. The experiment was performed using the AGATA $\gamma$-ray tracking array coupled to the magnetic spectrometer PRISMA [1-3].
    This setup allowed one to measure the...

  21. 68. (online) Superallowed $^{10}$C β-decay branching ratio measurement at INFN-LNL: report of Exp. 22. 72 and 24. 12
    Yonghyun SON (Seoul National University / Center for Exotic Nuclear Studies, IBS)
    16/09/2025 14:00

    We report preliminary results from the measurements of the superallowed $^{10}$C β-decay branching ratio with the AGATA HPGe tracking array at INFN-LNL. The precedent experiment, Exp. 22. 72 was performed in June 2023. A 10-MeV proton beam accelerated from the Tandem-XTU impinged to a 1-mg/cm$^2$-thick, Au-sandwiched $^{10}$B target. The experiment was run in two modes: in-beam mode and decay...

    Federico Simioni (UNIPD, INFN LNL)
    16/09/2025 14:20

    Inverse beta decay (IBD) is a crucial process historically employed to study neutrinos.
    For example, discrepancies between measured and expected IBD rates on ($^{71}\text{Ga}$), the so-called gallium anomaly, suggest the possible existence of sterile neutrinos. A recent publication showed that the poorly known associated Nuclear Matrix Element (NME) can be extracted measuring the decay...

  23. 12. Report on the AGATA experiment number 23.011
    Damiano Stramaccioni
    16/09/2025 14:40

    We present the preliminary analysis of an experiment performed at INFN LNL in November 2023 aimed at studying the two-octupole phonon collectivity in $^{96}$Zr. The goal of the experiment was to perform a $\gamma$-decay branching ratio measurement from the 6$^+$ to the 3$^-$ state, so as to extract the B(E3; 6$^+\rightarrow3^-$) value. If large, this parameter would indicate for the level to...

  24. 77. Search for a nuclear Josephson effect in 60Ni+116Sn sub-barrier transfer reactions with the PRISMA+AGATA set-up
    Giuseppe Andreetta (UNIPD, INFN PD)
    16/09/2025 15:00

    Sub-barrier transfer experiments have been recently carried out at LNL in the 60Ni+116Sn system, where the two neutron transfer channel is well Q-value matched. Reaction products have been detected in inverse kinematic and at forward angles with the large solid angle magnetic spectrometer PRISMA, providing high efficiency and resolution. In these studies one follows the behavior of the...
