Title: β -decay properties of the very neutron-rich isotopes Ge 86 and As 86

Abstract

For this research, the β -decay properties of very neutron rich nuclei 86Ge and 86As were measured at the Holifield Radioactive Ion Beam Facility at Oak Ridge National Laboratory. Spectroscopic information on new excited states in 86As and in 86Se was obtained and is interpreted within an advanced shell model approach. These calculations, previously explaining well the structure of 84Ge and 85Ge, are not able to reproduce all the experimentally determined features of the measured level schemes of 86As and 86Se. The Gamow-Teller decay of 86Ge and 86As is also investigated in a shell-model framework. The fission yield for 86Ge is discussed.
