Abstract
The one-body density-matrix elements obtained from the USDAHamiltonian are used to calculate the electronnucleus
scattering form factors for the 25Mg nucleus. The longitudinal form factor calculations produce good
agreements for all states in the first sequence whereas the shell-model predictions show a variation in results
for the excitation states in the second sequence. The wave functions of radial single-particle matrix elements
have been calculated with the Woods-Saxon, harmonic-oscillator, and Skyrme (Sk42) potentials. The results
of the inelastic transverse form factors are in good agreement with the experimental data when using the
Sk42 potential whereas the elastic magnetic scattering results show a significant difference in values compared
with the experimental data. However the overall shape and other features of the form factors are satisfactory
when using the harmonic-oscillator potential. The effective g factors were used as adjustable parameters in the
OXBASH code to describe the core-polarization effects in the transverse form factor calculations with the use of a
harmonic-oscillator size parameter in the elastic magnetic scattering.
