摘要

Lifetimes of levels in two doubly-decoupled bands of [Formula Presented] involving neutron intruder orbits have been measured using Doppler-shift techniques. The deduced transition quadrupole moments are consistent with total Routhian surface predictions for the suggested configurations of both bands. The negative-parity band with one neutron in the [Formula Presented] orbit has a much larger quadrupole deformation than the positive-parity band with a neutron in the [Formula Presented] orbit, reflecting the strong polarizing effect of the [Formula Presented] intruder orbit on the nuclear shape.
