The positive and negative-state bands of even–even 120–136Ba nuclei have been studied. The energy levels for the ground-state band of 120–136Ba have been calculated using Interacting Boson Model (IBM),
Interacting Vector Boson Model (IVBM) and a new method called Semi-Empirical Formula (SEF). The
negative parity band of even–even 120–136Ba isotopes has been also calculated using (IVBM) and (SEF).
The γ and β-bands of even–even 120–136Ba isotopes have been calculated using IBM and SEF. The parameters of the best fit to the measured data are determined. The reduced transition probabilities B(E2) of
these nuclei was calculated. The critical points have been determined for 134,136Ba isotopes.
The potential energy surfaces for even–even Ba isotopes are studied using the simplified form of Interacting Boson Model (IBM) with an intrinsic coherent state.
