Study of K = 0₂ low-lying energy levels in heavy mass nuclei

The present work is an extension of the study of deformation related physical quantity R_(4/2) in all low-lying energy levels written under g, β and γ bands in Sakai table in heavy mass nuclei. Interestingly the preliminary study of correlation of β - band with ground state band gives a clear message in Th, U and Pu nuclei that these are rigid rotors. In the present work we undertake the detailed calculations of energy levels of β - band employing a Soft Rotor Formula (SRF) believing that these are produced on account of rotation of asymmetric nucleus whose moment of inertia (MOI) and softness parameter (σ) are slightly different than that of MOI and σ of two other rotation which are producing yrast and γ - bands having low energies
