Study of positive parity states form factors for 17O nucleus with Skyrme-Hartree-Fock method

Abstract

Elastic and inelastic electron scattering form factors for the 17O nucleus are calculated for the positive parity low-lying states in the momentum transfer interval 0.05-3 fm in the framework of shell model and Skyrme-Hartree-Fock calculations. Also, protons, neutrons, mass and charges root mean square, r.m.s., radii and the charge spatial density distribution are calculated. The ZBME model space out of 12C nuclei core with rewile interaction have been used. For all selected ground and excited states, Skyrme interactions with SkXcsb and SLy4 parameter, harmonic and Wood-Saxon potentials are adopted in Hartree-Fock theory to generate the mean potential and hence calculate the elements of single-particle matrix and form factors. Also, we have used Tassie model to account for core-polarization effect. Finally, to check the reality of the calculated values, the charges r.m.s. and form factors are discussed and compared to the measured values. A good agreement can be shown by the theoretical results to the measured ones.
