4. Total absorption gamma-ray spectroscopy measurements for isospin mirror asymmetry and nuclear structure

Victor Guadilla Gomez (University of Warsaw (PL))

Invited (online)

In this contribution we will present recent experimental studies with the Lucrecia total absorption spectrometer at ISOLDE aimed at investigating the beta decays of nuclei of interest for nuclear structure. The Pandemonium effect [1] is known to hamper the determination of beta intensities with conventional HPGe approaches, while a high efficiency detector as Lucrecia [2] has proved the...

Very neutron-deficient nuclei in the vicinity of the $Z=82$ proton shell gap and the $N=104$ neutron mid-shell are well known for the interplay between single-particle and collective nuclear structure effects, such as shape coexistence and the systematic presence of low-spin isomeric states. This makes $Tl$ and $Hg$ isotopes highly interesting study cases within the shell model approach. With...

The Miniball array comprises eight clusters of three high-purity germanium detectors arranged around a reaction target located downstream of the HIE-ISOLDE beamline. The array measures gamma rays emitted following nuclear reactions of radioactive isotope beams of a few MeV per nucleon. Complimenting the Miniball array are beam-particle detectors and a newly-implemented conversion electron...

65. New results from the ISOLDE Decay Station

Invited (In person)

The ISOLDE Decay Station (IDS) [https://isolde-ids.web.cern.ch/] was designed as a flexible tool for decay spectroscopy studies, operating since 2014 at ISOLDE. At the core of IDS there are 4-6 HPGe clovers to detect γ rays with high energy resolution together with a moving tape system and a complex array of ancillary detectors such as LaBr3:Ce crystals to measure excited-state lifetimes down...
