Shell model calculations of inelastic electron scattering for positive and negative parity states in 19F

Shell model and Hartree-Fock calculations have been used to study the nuclear structure of 19F nucleus. In particular, inelastic electron scattering form factors, energy levels and transition probabilities for positive and negative low-lying states. Two different model spaces have been used for this purpose. The first is the full sd-model space for positive parity states with USDA interaction. The second one is the truncated large-basis spsdpf no-core-shell model space for negative parity states with WBP interaction except that in the extreme state 3/21− we used sdpf model space with SDPFK interaction. For all excited states, the radial wave functions for the single-particle matrix elements were calculated using the Skyrme-Hartree-Fock method with SkXcsb parameterization. The calculated form factors, energy level schemes and transition probabilities were compared with the available experimental data. It has been confirmed that the Hartree-Fock mean field method with Skyrme interaction is appropriate with shell model for studying the nuclear structure and essential in obtaining a reasonable description of the longitudinal and transverse electron scattering form factors.
