Charge density distributions and electron scattering form factors of 19F, 22Ne and 26Mg nuclei

Abstract

An effective two-body density operator for point nucleon system folded with the
tenser force correlations ( TC's), is produced and used to derive an explicit form for
ground state two-body charge density distributions (2BCDD's) applicable for
19F,22Ne and 26Mg nuclei. It is found that the inclusion of the two-body TC's has the
feature of increasing the central part of the 2BCDD's significantly and reducing the
tail part of them slightly, i.e. it tends to increase the probability of transferring the
protons from the surface of the nucleus towards its centeral region and consequently
makes the nucleus to be more rigid than the case when there is no TC's and also
leads to decrease the
1/ 2
2 r of the nucleus. It is also found that the effect of the
TC's and the effect of increasing the values of  on the 2BCDD's, elastic electron
scattering form factors and
1/ 2
2 r are in the same direction for all considered
nuclei.
