Beyond 132Sn: Examples of new data on exotic neutron-rich Te isotopes from fission and β-decay

Abstract

Exotic nuclei beyond the 132Sn double shell-closure have both single-particle and collective particlehole excitations and are expected to have competing excitation patterns from both type of excitations together with possible structural changes. We are, therefore, studying the region in the close vicinity beyond 132Sn and further with the neutron increase with experimental methods such as induced fission and β decay. A short overview of this knowledge will be given together with examples of newly obtained data at preliminary stage.
