Role of the Center of Mass Correction in Magnetic Form Factors for 19O and 21Na Exotic Nuclei with Different Interactions

Abstract

The transverse magnetic electron scattering form factors of 19O and 21Na exoticnuclei were studied in the plane wave Born approximation (PWBA). The shell modelcalculations with three sd-shell interactions, USDA, USDB, and Wildenthal, werecarried out for the ground and low-lying excited states. The exact center of masscorrection in the Born approximation picture through the translation-invariant shellmodel (TISM) was included to modify the transverse form factors. The measuredmagnetic dipole moments were well reproduced with the core polarization (CP) effectintroduced through the effective g-factors. The occupancies percentage with respectto the valence nucleons was also calculated.
