Abstract
Taking the concept of nuclear softness and the harmonic variable moment of inertia model VMI, were used to obtain a new formula ,denoted (VMINS model) which used in calculating the energies of rotational ground bands for some even-even nuclei. The predicted results of the VMINS model are in good agreements with the VMI result and the experimental data. Keywords: Softness, moment of inertia, angular momentum, rotational band
