摘要

It is known that elastic magnetic electron scattering can be used to study the magnetic properties of nuc-lei and determine the outermost-shell single-particle orbitals.In this study,the magnetic form factors |FM(q)|2 of odd-A nuclei calculated with relativistic and non-relativistic models are systematically compared.We use the relativ-istic mean-field (RMF) and Skyrme Hartree-Fock (SHF) models to generate single-particle wave functions and cal-culate the |FM(q)|2 values of selected nuclei under relativistic and non-relativistic frameworks,respectively.Geo-metric factors are introduced through the spherical limit method to consider the influences of deformation,which im-proves the agreement between the theoretical results and experimental data.It is shown that both the models have the capability to describe the magnetic form factors in the spherical and deformed cases,and the discrepancies in|FM(q)|2 reflect the differences in the descriptions of the single-particle orbital between the two models.
