Shell model calculations in ⁹⁶Tc

Nuclei with neutron number in vicinity of the major shell closure at N= 50, and the proton number lying between the semi-closed Z= 40 and the closed Z= 50 shells pro- vide particularly good laboratories to probe the weakly deformed nuclei. Theoretical interpretations of level structures from new spectroscopic studies in these nuclei have revealed novel deformation-generating mechanisms. The nuclei approaching the neutron and proton major shell closures at N=Z=50 provide a unique opportunity to study interplay between the single-particle and collective degrees of freedom, and influence of the valence orbitals on deformation. Various new deformation generating mechanisms have been identified in theoretical interpretation of the observed band structures. Theoretical interpretations of level structures from new spectroscopic studies in these nuclei have revealed novel deformation-generating mechanisms. The details of the wave functions for the excited higher spins states of positive parity states of ⁹⁶Tc corresponding to the experimental ones are in agreement, and will be presented
