The Backbending Phenomenon in Deformed Even-Even Nuclei for 180,182W Isotopes

Abstract

180, 182W isotopes near mass region A~180 which exhibit features of the SU(3)-O(6) symmetry at low energy and the backbending phenomenon at high spin , are studied in the framework of the interacting boson model (IBM-1) . Reasonable agreement was obtained between our theoretical calculations and the most recent experimental data. The backbending phenomenon was noticed both experimentally and theoretically and they were in good agreement.
