Abstract
Nuclear structure (energy levels, elastic and inelastic electron-nucleus scattering, and transition probability) of
23Na, 25Mg, 27Al, and 41Ca nuclei have been studied using shell-model calculations.Aset of two-body interactions
are used in this paper. The universal sd of the Wildenthal interaction in the proton-neutron formalism, universal
sd-shell interaction A, universal sd-shell interaction B, and GXFP1 interaction for the fp shell is used with the
nucleon-nucleon realistic interactionMichigan three-rangeYakawa as a two-body interaction for core-polarization
calculations. Two shell-model codes, CPM3Y and NUSHELL for Windows, have been used to calculate the results.
The wave functions of radial single-particle matrix elements have been calculated with harmonic-oscillator and
Woods-Saxon potentials. The level schemes are compared with the experimental data up to 5.776, 5.251, and
4.51 MeV for 23Na, 25Mg, and 27Mg, respectively. Very good agreements are obtained for all nuclei in this
study. Results from electron scattering form-factor calculations have shown that the core-polarization effects are
essential to obtain a reasonable description of the data with no adjustable parameters.
