The Deformation Structure of the Nuclei 32S and 36Ar

Abstract

We applied two different approaches to investigate the deformation structures of the two nuclei S³² and Ar³⁶ . In the first approach, we considered these nuclei as being deformed and have axes of symmetry. Accordingly, we calculated their moments of inertia by using the concept of the single-particle Schr dinger fluid as functions of the deformation parameter β. In this case we calculated also the electric quadrupole moments of the two nuclei by applying Nilsson model as functions of β. In the second approach, we used a strongly deformed nonaxial single-particle potential, depending on Î² and the nonaxiality parameter γ , to obtain the single-particle energies and wave functions. Accordingly, we calculated the quadrupole moments of S³² and Ar³⁶ by filling the single-particle states corresponding to the ground- and the first excited states of these nuclei. The moments of inertia of S³² and Ar³⁶ are then calculated by applying the nuclear superfluidity model. The obtained results are in good agreement with the corresponding experimental data.
