Level structure of $^{86}$Sr

The high-spin states in 86Sr have been investigated by using in-beam \( \gamma\)-ray spectroscopy with the 82Se(9Be, 5n)86Sr reaction at a beam energy of 53 MeV. The level scheme of 86Sr has been extended considerably, four decay sequences have been established. The observed level schemes are compared with shell-model calculations using the recently developed residual interaction “jun45”, and a good agreement is shown.
