Title: Comparative lifetimes of superdeformed bands in A{approx}80 Nuclei

Abstract

A comparative measurement of the transition quadrupole moments of the yrast superdeformed bands in {sup 80-83}Sr, {sup 83}Y, {sup 84}Zr has been performed using the Doppler-shift attenuation method. Thus, we have accurately measured the relative deformations of these structures, establishing for the first time, clear trends in the deformations of these bands. The yrast SD bands in the {sup 80-83}Sr isotopes are shown to possess similar transition quadrupole moments, while significantly larger values are obtained for the {sup 83}Y and {sup 84}Zr cases. These results provide a stringent evaluation of the intruder orbital assignments of these structures, suggesting new assignments in some of these cases. (c) 1999 American Institute of Physics.
