The energy levels, B(E2) values, the square of rotational energy and the moment of inertia, staggering in γ- band energies andthe potential energy surface for184,186Osisotopes have been investigated using IBM-1. The calculated results good agreement with experimental data

Shape Transition and Collective Excitations in 166-180Hf Isotopes

journal of kerbala university, Volume 5, Issue 2, Pages 95-106

The low-lying collective levels in 166-180Hf isotopes are investigated in the frame work of the interacting boson model (IBM-1). The contour plot of the potential energy surfaces, V (), shows two wells on the prolate and oblate sides which indicate that all hafnium nuclei are deformed and have rotational characters. The levels energy, electromagnetic transition rates B(E2) and electric quadrupole moment [ ] are calculated. All calculated values are compared with the available experimental data and show reasonable agreement
