Pronounced shape change induced by quasiparticle alignment
2000
Physical Review C
Mean lifetimes of high-spin states of 74 Kr have been determined using the Doppler-shift attenuation method. The high-spin states were studied using the 40 Ca( 40 Ca,␣2p) reaction at a beam energy of 160 MeV with the GASP ␥-ray spectrometer. The ground-state band and negative parity side band show the presence of three different configurations in terms of transitional quadrupole deformations. A dramatic shape change was found along the ground-state band after the S-band crossing. The deduced
