The beta delayed fission (βDF) (EC/β + ) is a rare nuclear process which couples fission and beta decay. In this process, a parent nucleus undergoes beta decay, possibly populating high-lying states in the daughter nucleus, close to the top of the fission barrier, thus allowing the fission of the daughter to be competitive with other decay modes.
This process is expected to occur in the heavy...

There is considerable theoretical and experimental evidence that atomic nuclei can assume reflection asymmetric shapes that arise from the octupole degree of freedom [1]. The associated phenomena that is observed include odd-even staggering of the positive- and negative-parity yrast bands in even-even nuclei, parity doublets in odd mass nuclei [2,3], and enhanced E1 moments due to a division...

One of the goals of modern nuclear physics research is to understand the origin of coexisting nuclear shapes and exotic excitations and their relation to the fundamental interactions between the nuclear constituents. These subjects can be investigated particularly well in the Pb isotopes close to neutron mid-shell, where a relatively small proton shell gap, together with a large valence...

Total Absorption Spectroscopy (TAS) is an essential technique to measure beta decay BGT distributions free of systematic errors (“Pandemonium Problem”).The TAS spectrometer “Lucrecia” , the largest TAS spectrometer presently operating, was installed at ISOLDE with this purpose. The scientific programme so far has been focused on the investigation of ground states nuclear shapes. They are...

Over the last two years a new experimental beam line has been designed and installed to perform collinear resonant ionization spectroscopy (CRIS) experiments at ISOLDE. The initial series of experiments will study the francium isotopes up to and including 201Fr and 218,219Fr. This work aims at answering questions on the ordering of quantum states, and effect of the 1/2+ intruder state, which...
