الملخص الإنجليزي

Inelastic longitudinal electron scattering form factors ofCa48 has been investigated in the framework of Microscopic theory.

The investigations have been performed in terms of the configuration mixing shell model with limiting number of orbital in the model space outside the inert core.

The discarded space has been included, which is called core-polarization effects, which considers particle-hole excitations from the core orbits and from the model space orbits into the higher orbits with 2ħω excitation energy.

The sigma meson of two body Michigan sum of three range Yukawa potential (M3Y) interaction has been utilized as a residual interaction.

The FPD6 model space was used as an effective interaction to generate the model space wave functions.

The simple harmonic oscillator potential is used as a single particle wave functions where an analytical solution is possible.

The effective fitting interaction parameter was produced using the sigma(δ) mesons exchange between two nucleons by using inelastic electron scattering from the multiple transition (C0,C2 and C4) to five excitation energy levels for C2 and C4, in fp-model space of P 48 PCa by seven(E,P0,P1,P2,P3,P4 and P5) Yukawa potential interaction (M3Y-type).

The C0, C2 and C4 form factors are enhanced by including core-polarization effects, where previous studies give effective charges greater than those of free space, to account for the core polarization effects.
