Electron Scattering from Some Fp- Shell Nuclei with Inclusion the Effect of Short-Range Correlation

Abstract

The effects of short-range correlation on elastic Coulomb (charge) form factors, charge density distributions as well as root mean square charge radii of various  nuclei (for instance, ^{46, 48, 50}Ti, ^{52, 54}Cr, ^{56, 58}Fe, and ^{72, 74, 76}Ge nuclei) are examined. The one- and two body terms of the cluster expansion together with the single-particle harmonic oscillator wave functions are utilized. For the purpose of embedding these effects into the formulae of charge density  and form factor  we employ the correlation function of Jastrow-type. These formulae depend upon the short-range correlation parameter  (which instigates from the Jastrow function) and the oscillator size parameter   Both  and  are found by the fitting to the measured elastic form factors. It is noticed that the embedding of short-range correlation effects into the calculations of  and  is a requisite for the achievement of a vital change in the computed results and remarkably vital for the characterization of the measured data.
