The deformation structure of the even-even p- and s-d shell nuclei

الملخص EN

In order to investigate the deformation structure of the even-even p- and s-d shell nuclei: 8Be, 12C, 20Ne, 24Mg 28Si, 32S and 36Ar, we have calculated two characteristics for these nuclei by using different models that depend on the shape of the nucleus.

In the case where the nucleus is assumed to be deformed and has an axis of symmetry, we have applied the concept of the single-particle Schrödinger fluid for the calculation of the nuclear moment of inertia together with the usual method of calculating the electric quadrupole moment in this case.

In the case where the nucleus is assumed to be deformed and has not an axis of symmetry, the nuclear superfluidity model and the cranked Nilsson model are applied for the calculations of the moments of inertia and the quadrupole moments of these nuclei, respectively.

The analysis of the obtained results showed that some of these nuclei may have axes of symmetry.
