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.
