Lifetimes of levels in two doubly-decoupled bands of 134Pr 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 i13/2 orbit has a much larger quadrupole deformation than the positive-parity band with a neutron in the (f7/2/h9/2) orbit, reflecting the strong polarizing effect of the N=6 intruder orbit on the nuclear shape.

Abstract
Lifetimes of levels in two doubly-decoupled bands of 134Pr 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 i13/2 orbit has a much larger quadrupole deformation than the positive-parity band with a neutron in the (f7/2/h9/2) orbit, reflecting the strong polarizing effect of the N=6 intruder orbit on the nuclear shape.
