Abstract
Gamma-ray cascades from nanosecond isomers in neutron-rich nuclei and have been observed through heavy-ion deep-inelastic collisions of (8 MeV/nucleon) using an isomer-scope. In an isomeric state at 3464 keV and its decay scheme have been established. The isomeric transition is a hindered transition between the and the states with main components of and respectively. A fast transition between the and the single-particle states indicates strong particle-octupole vibration coupling in An isomeric state at 834 keV with has been identified in Proton-neutron configurations of the levels established in are discussed.
