Charge density distributions and electron scattering form factors of 25Mg, 27Al and 29Si nuclei

Abstract EN

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 25Mg, 27Al and 29Si 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 r 2 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 r2 1/ 2 are in the same direction for all considered nuclei.
