Core Collapse Supernova (CCSN) explosion is the final process suffer by starts with initial mass greater than 8 M⨀. In such processes the 44Ti nucleosynthesis takes place, doing the isotope a good gamma tracer of Supernovae events, due to its characteristic gamma decay chain. The comparison between observations and models of the synthetized 44Ti in CCSN gives important constrains to the models...

14. An electrostatic trap for high sensitivity, on-line laser spectroscopy

Collinear laser spectroscopy coupled with optical pumping, within the cooler-buncher, has proved a highly successful technique at IGISOL-4 (and at the previous IGISOL-3) [1-3] and has facilitated spectroscopy on manganese, niobium, yttrium and even the doubly charged yttrium ion. The technique is however critically limited by conditions within the cooler-buncher. The pumping, while highly...

13. beta-delayed neutron emission and half-lives measurements with a 4pi neutron detection setup: BELEN and BRIKEN detectors

List of posters

$\beta$-delayed neutron emissions play a crucial role in various fields, including nuclear technology and nuclear astrophysics. Our research group boasts extensive expertise in measuring $\beta$-delayed one and two neutron emission probabilities ($P_{1n}$ and $P_{2n}$ values), as well as decay half-lives of exotic nuclei, utilizing the state-of-the-art BELEN and BRIKEN (Beta delayed neutron...

11. Development and commissioning of new Decay Spectroscopy Station at CRIS with 75Zn

List of posters

Laser spectroscopy can study many ground-state properties (spin, nuclear electromagnetic moments, changes in the charge radius) of the nucleus which can challenge state-of-the-art nuclear models, and enhance our understanding of the nuclear forces. Furthermore, its application at ISOL facilities can give access to the same properties of long-lived states (>10ms). One major challenge that laser...

12. Molecular laser spectroscopy of RaF at CRIS

List of posters

In the past few years, the spectroscopy of radioactive molecules has been performed at ISOLDE (CERN) using the Collinear Resonance Ionization Spectroscopy (CRIS) experiment [1]. Given their structure and chemical properties, molecules are a promising candidate for studies in different fields [2] and for extracting elements with low production yields due to their refractory or reactive...

10. RIALTO, the Resonant Ionization Laser Ion Source at ALTO

List of posters

RIALTO, the Resonant Ionization Laser Ion Source at the ALTO facility, uses a multi-step laser excitation process to produce pure ion beams through the resonance ionization technique.
The laser laboratory is equipped with three high-power Nd:YAG operating at 10 kHz and pumping three dye lasers; these lasers are coupled with BBO doubling units and one tripling unit; this laser system allows us...

6. Technical progress at the double Penning trap PIPERADE

List of posters

The double Penning trap PIPERADE (PIèges de PEnning pour les RAdionucléides à DESIR) [1] for the DESIR facility has been advancing in its commissioning phase at the LP2i-Bordeaux laboratory. The traps were designed with the objective of performing high-precision mass measurements and high-resolution mass purification of strongly contaminated ion beams. The latter will be produced by the...

4. Testing the Standard Model with the WISArD Experiment

List of posters

The objective of the WISArD experiment is to test the existence of new physics in the weak interaction sector of the Standard Model of particle physics using beta decay. The goal of the WISArD experiment is to measure the angular correlation parameter a and the Fierz interference term b in the decay of 32Ar with a precision of about 0.1%, in order to provide constraints on new physics that...
