The effect of short range correlation on the inelastic C4 form factors of 18O nucleus
The effect of short range correlations on the inelastic longitudinal Coulomb form factors for different states of J 4 , T 1with excitation energies 3.553,7.114, 8.960 and 10.310 MeV in 18O is analyzed. This effect (which depends on the correlation parameter ) is inserted into the ground sta...

The effect of short range correlations on the inelastic longitudinal
Coulomb form factors for different states of J 4 , T 1with
excitation energies 3.553,7.114, 8.960 and 10.310 MeV in 18O 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 b.
The parameters 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 factors 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.
