## Abstract

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