In this work, we present recent lifetime measurements in exotic nuclei performed at Institut Laue-Langevin in different 235U neutron-induced fission campaigns, using the Lohengrin spectrometer and a hybrid setup made of HPGe clover detectors and LaBr3(Ce) scintillators. In particular, results on the neutron-rich 131Sb and 96Rb isotopes will be discussed, which have implications on the origin of collectivity around the doubly magic 132Sn nucleus and the shape-coexistence phenomenon around N = 60, respectively.

Abstract

In this work, we present recent lifetime measurements in exotic nuclei performed at Institut Laue-Langevin in different 235U neutron-induced fission campaigns, using the Lohengrin spectrometer and a hybrid setup made of HPGe clover detectors and LaBr3(Ce) scintillators. In particular, results on the neutron-rich 131Sb and 96Rb isotopes will be discussed, which have implications on the origin of collectivity around the doubly magic 132Sn nucleus and the shape-coexistence phenomenon around N = 60, respectively.
