Description
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 use of the ISOLDE Decay Station (IDS) detector set-up equipped with 6 HPGe clover detectors, 3 LaBr$_3$(Ce) detectors and fast plastic scintillators, measurements were performed for the extracted $^{181,183,184,185,187}Tl$ isotopes(in their ground and isomeric states), as well as their associated decay chains. The report will focus on some preliminary results of the spectroscopic investigation which includes lifetime measurements through the electronic fast-timing method.
