This nucleus is described as a core of with 6 active protons move in the space of The OXBASH shell-model program together with the interaction of are used to obtain the excitation energies in To reflect the transition from regular (ordered) to chaos in , we consider different strengths parameter to the off diagonal elements of The level density for the states is found to have a Gaussian shape, which is in agreement with the predicted studies for a many-body system with two-body residual interaction. Both distributions for the level spacing and statistics show an ordered performance at strength parameter a chaotic performance at and an in-between situation at
