| The effect of short range correlations on the inelastic Coulomb form factors for excited states (1.982, 3.919, 5.250 and 8.210MeV) and states (3.553, 7.114, 8.960 and 10.310 MeV) in is analyzed. This effect (which depends on the correlation parameter ) is inserted into the ground state charge density distribution through the Jastrow type correlation function. The single particle harmonic oscillator wave function is used with an oscillator size parameter The parameters and are adjusted for each excited state separately so as to reproduce the experimental root mean square charge radius of The nucleus is considered as an inert core of withtwo protons and four neutrons distributed over active orbits. The total transition charge density comes from both the model space and core polarization transition charge densities.The realistic effective interaction of Reehal–Wildenthal (REWIL) is used for this model space. It is found that the introduction of the effect of short range correlations is necessary for obtaining a remarkable improvement for the calculated inelastic Coulomb form factors and considered as an essential for explanation the data amazingly throughout the whole range of considered momentum transfer. | ||
