Abstract EN
The effect of short range correlations on the inelastic longitudinal Coulomb form factors for the lowest four excited 2+ states in 18O is analyzed.
This effect (which depends on the correlation parameter β) 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 b.
The parameters β and b are, considered as free parameters, adjusted for each excited state separately so as to reproduce the experimental root mean square charge radius of 18O.
The model space of 18O does not contribute to the transition charge density.
As a result, the inelastic Coulomb form factor of 18O comes absolutely from the core polarization transition charge density.
According to the collective modes of nuclei, the core polarization transition charge density is assumed to have the form of Tassie shape.
It is found that the introduction of the effect of short range correlations is necessary for obtaining a remarkable modification in the calculated inelastic longitudinal Coulomb form factors and considered as an essential for explanation the data amazingly throughout the whole range of considered momentum transfer.
