Abstract
Inelastic transverse magnetic dipole electron scattering formfactors in 48Ca have been investigated through nuclear shell modelin an excited state energy Ex= 10.23 MeV which is so called"mystery case" with different optional choices like effectiveinteraction, restricted occupation and core polarization interaction.40Ca as an inert core will be adopted and four orbits with eightparticles distributed mainly in 2p1f model space and in some extendrestricted to make sure about the major accuse about this type oftransition. Theoretical results have been constituted mainly withexperimental data and compared with some important theoreticalresults of the same transition.
Highlights
In order to understand the nuclear forces and the laws that control the interactions of elementary particles, the scattering of variety of particles by a variety of targets is the only available technique [1]
Richter in (2005) [7] through his work on magnetic dipole and GamowTeller modes: quenching, fine structure and astrophysical implications demonstrated that high-precision M1 data on N = 28 isotones from electron scattering at Darmstadt permit the extraction of neutral-current neutrinonucleus scattering cross sections important for supernova dynamics and nucleosynthesis, by the use of the technique Random Phase Approximation technique (RPA) and he modified his theory by the use of SRPA +(π+ ρ) meson exchange between the two particle -two hole states with 4ħω excitation and his results are nearly in a good agreement with the experimental data
A computer program is written in FORTRAN 90 language to include realistic interaction the Michigan three Yukawa (M3Y) in the original code to calculate the model space form factors and the first-order core polarization effects

A computer program is written in FORTRAN 90 language to include realistic interaction the Michigan three Yukawa (M3Y) in the original code to calculate the model space form factors (zero-order) and the first-order core polarization effects. According to the first order perturbation theory, the single-particle matrix element for the higher-energy configurations is given by [8] :
