First observation of -soft and triaxial bands in Zr isotopes
Abstract
New results obtained in this work from measurements of γ radiation following fission of 248Cm and 252Cf, performed using Eurogam2 and Gammasphere arrays, respectively, reveal excitations corresponding to γ vibrations and triaxial deformation present in 100Zr and 102Zr nuclei. This is the first observation of nonaxial bands in Zr isotopes. Such excitations probably occur due to competing prolate and oblate configurations, identified recently in these nuclei. Evolution of γ softness and triaxiality in Zr isotopes is observed in the function of the neutron number.
