Beta decay of neutron rich nuclei is particularly important for many fields in fundamental and applied physics. In nuclear reactors, the beta decay of fission products is responsible for additional power, the decay heat, and anti-neutrino emission. In nuclear astrophysics, the r-process is a process at the origin of the nucleo-synthesis of half of the nuclei heavier than iron. In both cases, beta decay plays a major role. A precise knowledge of the properties of beta decay can constrain the theoretical models used to understand these processes.

Some of the nuclei involved in these two fields of nuclear physics are affected by the pandemonium effect: a noxious effect coming from the detection efficiency leading to a distortion of the beta decay feeding and affecting nuclear databases.

New measurements of a series of nuclei relevant for the above mentioned topics have been performed at the IGISOL facility in Jyväskylä, Finland, in September 2022, using Total Absorption Gamma Spectroscopy (TAGS) technique which is a complementary to the high-resolution gamma-ray spectroscopy.
