Systematic Investigation Of Gamma-Band Structure Of Triaxial Even-Even Neutron-Deficient Os Nuclei

gamma-bands built on triaxial deformation of neutron-deficient even-even Os isotopes in the A similar to 180 region, are well investigated in the present work within the self-consistent quantum mechanical framework known as triaxial projected shell model (TPSM). The TPSM results on yrast, gamma-, 2 gamma-bands provide a reasonable description about the triaxial nature of the isotopes. Moreover, the deformation systematics, back-bending in moment of inertia, energy ratios, transition probabilities and g-factors have also been calculated and compared with the known experimental data and, a considerable good agreement has been achieved between the two.
