Shape changes induced by quasiparticle alignment

Mean lifetimes of high-spin states of {sup 74}Kr have been determined using the Doppler shift attenuation method (DSAM). The high-spin states were studied using the {sup 40}Ca({sup 40}Ca,{alpha}2p) reaction at a beam energy of 160 MeV with the GASP array. The investigated ground state band and negat...

Zusammenfassung:Mean lifetimes of high-spin states of {sup 74}Kr have been determined using the Doppler shift attenuation method (DSAM). The high-spin states were studied using the {sup 40}Ca({sup 40}Ca,{alpha}2p) reaction at a beam energy of 160 MeV with the GASP array. The investigated ground state band and negative parity side band show the presence of three different configurations in terms of transitional quadrupole deformations. The deduced quadrupole deformation changes are well reproduced by cranked Woods-Saxon Strutinsky calculations.
