“…This modification has produced more theoretical values which agree with the experimental data within the range of q < 1 fm −1 . This behavior is similar to that found in adding the core-polarization effects [33]. The opposite behavior of the M3 values makes the theoretical results more appropriate in the lower range.…”

“…Experiments have been performed by Euteneuer et al [29] for a momentum transfer range from 0.19 to 2.56 fm −1 . Euteneuer et al [29] have examined the effective momentum transfer values q eff defined by the equation [18], [31], the shell-model using the cwc interaction, and the Woods-Saxon wave functions (curve 3) [32], and the shell-model with the core-polarization effects with the harmonic-oscillator potential reduces the b rms value by 5% (curve 4) [33].

The one-body density-matrix elements obtained from the USDA Hamiltonian are used to calculate the electronnucleus scattering form factors for the 25 Mg 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.

“…Similarly to the case of charge scattering, magnetic scattering has been also studied in stable nuclei from different theoretical frameworks [7], including shell model [28][29][30][31], relativistic mean field [32][33][34][35], and deformed mean field models [8,9,[36][37][38][39][40].…”

Elastic magnetic electron scattering from deformed nuclei

et al. 2019

Magnetic form factors corresponding to elastic electron scattering from odd-A nuclei are presented. The calculations are carried out in plane-wave Born approximation. The one-body properties are obtained in a deformed self-consistent mean-field calculation based on a Skyrme HF+BCS method. Collective effects are also included in the cranking approximation. Results on several stable nuclei are compared with the available experimental information. It is shown that a deformed formalism improves the agreement with experiment in deformed nuclei, while reproducing equally well spherical nuclei by taking properly the spherical limit of the deformed model and the effect of nucleon-nucleon correlations. Thus, the capability of the model to describe magnetic form factors is demonstrated. This opens the door to explore also unstable nuclei of particular interest that could be measured in future experiments on electron-radioactive beam colliders.
