Disentangling decaying isomers and searching for signatures of collective excitations in beta decay

In this contribution we summarize the recent study of the beta decay of neutron-rich nuclei with isomeric states close in energy to the ground states. The disentanglement of each pair of beta-decaying states was achieved by applying different strategies and using the purification capabilities of the...
