Abstract

High-spin states in [Formula Presented]Kr were identified via analysis of prompt [Formula Presented]-[Formula Presented] coincidences in the [Formula Presented]Ni[Formula Presented]Si,[Formula Presented] reaction at 128 MeV at the Gammasphere facility. Evaporation channel selection was achieved using the 95 element Microball charged-particle detector. 27 new states and 42 new transitions were found. The positive-parity bands were confirmed and the [Formula Presented][Formula Presented] band extended to [Formula Presented]. The negative-parity signature pair was extended to [Formula Presented] and [Formula Presented]. Two new high-lying negative-parity bands were found extending from a state of spin [Formula Presented][Formula Presented] and energy 2.6 MeV to 17.4 MeV at [Formula Presented]. The new bands appear highly deformed and become yrast at high spin. A three-quasiparticle structure based on deformation driving, low-[Formula Presented] unique-parity and intruder orbitals is suggested for them.
