  57. 73. Report on AGATA@LNL experiment 23.08: Coulomb excitation of 60Ni
    Kasia Hadynska-Klek (Heavy Ion Laboratory University of Warsaw)
    12/09/2024 15:00
    ACC

    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 [3]. However,...

    ACC

    In this contribution, we will present the current state of the analysis of experiments 23.07 and 23.09 studying the 56Ni and 60Zn 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....

  63. 63. Lifetime measurement of astrophysically relevant 6.793 MeV state of 15O
    Elia Pilotto (University of Padova)
    13/09/2024 09:00
    ACC

    In this contribution, we will present the current state of the analysis of experiment 23.003, aimed at the measurement of the lifetime of the 6.793 MeV excited state of 15O with sub-fs uncertainty. This experiment has strong astrophysical implications, as the lifetime we aim to measure strongly influences the value of the S-factor at Gamow-window energies for stars like our Sun. The experiment...

  64. 65. Spectroscopy and lifetime measurements toward the Island of Inversion with the AGATA-PRISMA setup
    Davide Genna (Università degli Studi di Milano & INFN Sezione di Milano)
    13/09/2024 09:15
    ACC

    We present recent AGATA-PRISMA results on multi-nucleon transfer reactions induced by 22Ne and 26Mg beams on a 238U target at LNL. The experiments aim at exploring the boundaries of the N = 20 Island of Inversion by following the evolution of negative parity states originating from fp shell excitations, locating excited intruder configurations, and tracking the...

  65. 71. 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)
    13/09/2024 09:30
    ACC

    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 aim of the experiment here presented was 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...

  66. 69. Report on AGATA experiment 001 phase 2 (LNL PAC: 22.07)
    Luca Zago (University of Padova, INFN LNL)
    13/09/2024 09:45
    ACC

    The disappearance of the N=20 shell closure in the so-called “island of inversion” around $^{32}$Mg is one of the most striking examples of the strength of nucleon-nucleon correlations. In this region, the quadrupole-deformed intruder configuration (based on a multi-particle multi-hole configuration) becomes the ground state, subverting the expected shell ordering predicted by a harmonic...

    Giuseppe Andreetta (UNIPD, INFN LNL)
    13/09/2024 10:00
    ACC

    The pairing interaction, responsible for the two-nucleon correlation, plays a fundamental role in defining the low-energy spectra of atomic nuclei and the properties of their ground state. The effect of pairing correlations in the reaction dynamics can be explored by using heavy-ion reactions, in particular those involving a transfer of few nucleons. In this context, an interesting analogy...

    Magdalena Zielinska (CEA Saclay)

    ACC

    The experiment 22.18 was performed to study the nucleus $^{96}$Zr utilising the $\gamma$-ray tracking spectrometer AGATA coupled with the heavy-ion detector array SPIDER at INFN-LNL. This experiment is extremely timely in order to provide directly the $3^-_ 1 \rightarrow 0^+_1$ $\gamma$-ray transition probability for the first time. Previous measurements suggested that the $\gamma$-ray...

  69. 3. Two-Phonon Octupole excitation in 96Zr
    Damiano Stramaccioni

    ACC

    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; $6^+ \rightarrow 3^-$) value. If large, this parameter would indicate for the $6^+$...

    In this talk, I will report on the recent “Combined lifetime and transition-probability measurements in 96Zr via Coulomb excitation” experiment, conducted using the AGATA + PRISMA + Plunger detector setup during the May 23-29, 2024 beamtime. The primary aim of the...

  71. 66. Investigating shape coexistence in Z≈N A≈70 nuclei using Coulomb excitation of selenium-74
    Robin Kjus (CEA Saclay)
    13/09/2024 11:30
    ACC

    The neutron-deficient selenium and krypton have been observed to exhibit a wide range of shapes which can be linked to large shell gaps. Typically, for even-even nuclei in this region, the ground states are of prolate deformation with oblate states built on a deformed $0^+$ state. However, certain nuclei, such as krypton-72 and selenium-68, are suggested to have the reverse configuration,...

  72. 76. Report on AGATA@LNL experiment E22.41 "Probing Multiple Shape Coexistence in 110Cd with Coulomb Excitation"
    Iwona Piętka (Heavy Ion Laboratory, University of Warsaw, Warsaw, Poland)
    13/09/2024 11:45
    ACC

    For several decades, stable even-mass Cd isotopes have been considered to be textbook examples of multiphonon spherical vibrators [1] based on the excitation energy pattern of their low-lying states. However, a detailed study of $^{110}$In $\beta$ decay and subsequent beyond-mean-field theoretical calculations [2-5] suggested instead the presence of multiple shape coexistence in $^{110}$Cd...

    ACC

    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...

    With the AGATA-PRISMA setup at INFN Legnaro, the experiment "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" was carried out to measure excited states to answer open questions in these regions of the nuclear chart.

  75. 68. Analysis of EXP-017 and EXP-022: Challenges, Solutions, and Future Directions
    Conor Sullivan (University of Liverpool)
    13/09/2024 12:30
    ACC

    This presentation explores results from two experiments, EXP_017 (23.015) and EXP_022 (22.096), focussing on high-spin states in $^{136,137}$Nd and octupole deformation in uranium isotopes, respectively.

    In EXP_017, the investigation centered on the decays out of highly deformed rotational bands in $^{136}$Nd and $^{137}$Nd. These bands challenge existing nuclear structure theories by...

  76. 72. Report on the data analysis of the experiment 23.015 devoted to the search for the decay-out of the oblate, triaxial and highly-deformed bands in 136,137Nd
    Costel Petrache (IJClab Université Paris Sud and CNRS/IN2P3)
    13/09/2024 12:45
    ACC

    The experiment 23.015 performed in October 21-26, 2023 was devoted to the search for the decay out of an extremely regular rotational band in $^{137}$Nd, interpreted as built on oblate shape, that extends to a spin of about 75/2 and an excitation energy of 4.5 MeV above yrast at the highest spins. We measured 7 days with the $^{33}$S+$^{110}$Pd reaction at 180 MeV and the AGATA+EUCLIDES setup....

    Hamid Ayatollahzadeh (University of the West of Scotland)

    ACC

    Recent calculations have suggested that the region of strong octupole correlations in the
    light actinides extends to higher Z values than previously thought, with neutron-deficient
    plutonium (Z = 94) and curium (Z = 96) nuclei predicted to have large β 3 values in their
    ground states [1, 2]. In order to test the predictions, an experiment has been performed
    to study the structure of...
