Theoretical Study of Nuclear Density Distributions and Elastic Electron Scattering Form Factors of Some Proton Halo Nuclei (17Ne and 8B)

Theoretical investigation of proton halo-nucleus ( 8 B and 17 Ne) has revealed that the valence protons are to be in pure (1p 1/2 ) 1 orbit for 8 B and (1d 3/2 ) 2 orbit for 17 Ne.  The nuclear matter density distributions, the elastic electron scattering form factors and (proton, charge, neutron and matter) root-mean square (rms) are studied for our tested nuclei, through an effective two-body density operator for point nucleon system folded with two-body full correlation operatoru0027s functions. The full correlation (FCu0027s ) takes account of the effect for the strong short range repulsion (SRCu0027s) and the strong tensor force (TCu0027s) in the nucleon-nucleon forces. The effective two-body density operator is produced and used to derive an explicit form for ground state two-body nucleon density distributions (2BNDDu0027s) applicable for proton – rich halo nuclei and Fortran 95 programs are utilized to obtain theoretical values of our calculation. The effect of the TCu0027s and SRCu0027s on the ground state also calculated. 2BNDDu0027s obtained within the two- frequency shell model (TFSM) approach, the elastic charge scattering form factors F(q) u0027s of proton halo nuclei are studied through Plane Wave Born Approximation (PWBA) .
