Abstract
A detailed study of very neutron deficient nuclei with (Sr,Zr) and has been carried out. Total potential energy surfaces taking into account both quadrupole and hexadecapole deformation have been calculated for the Zr () nuclei, starting from the Nilsson model. Also oddmass nuclei have subsequently been studied when coupling the odd particle to the deformed even-even core. After extensive band mixing calculations for the nucleus, comparison to the existing experimental data [energy spectra for positive and negative parity [422] and [301] bands; static moments , ; mixing ratios and branching ratios] has been carried out. We have also concentrated on the excited state properties of even-even Sr nuclei within the framework of the interacting boson model. A critical analysis of the interacting boson model parameters, as obtained from calculations in nearby nuclei, i.e., , is carried out, especially for the behavior of , and .
