Elastic electron scattering form factors, charge density distributions and charge,

PS nuclei are
studied using the effect of occupation numbers. Single-particle radial wave functions
of harmonic-oscillators (HO) potential are used. In general, the results of elastic
charge form factors showed good agreement with experimental data. The occupation
numbers are taken to reproduce the quantities mentioned above. The inclusion of
occupation numbers enhances the form factors to become closer to the data. For the
calculated charge density distributions, the results show good agreement with
experimental data except the fail to produce the hump in the central region for P

nucleus. Finally, the calculated charge rms radii for the nuclei under study show
good agreement with experimental data.
