Shape evolution of the highly deformed {sup 75}Kr nucleus examined with the Doppler-shift attenuation method
Abstract
High-spin states of the {sup 75}Kr nucleus have been populated via the {sup 50}Cr({sup 28}Si,2pn){sup 75}Kr reaction at an incident beam energy of 90 MeV. Lifetimes of nine states up to spin I=33/2 for the positive-parity band and seven states up to I=27/2 for the negative-parity band have been measured using the Doppler-shift attenuation method. The deduced transition quadrupole moments Q{sub t} of these bands have been compared to the projected shell-model calculations to gain insight into the evolution of collectivity for the two experimentally studied bands in {sup 75}Kr.
