Calculation of the longitudinal electron scattering form factors for the 2s-1d shell nuclei

Abstract EN

Inelastic longitudinal electron scattering form factors have been calculated for isoscaler transition T = 0 of the (0+ → 2+ ) and (0+ → 4+ ) transitions for the 20Ne, 24Mg and 28Si nuclei.

Model space wave function defined by the orbits 1d5 2, 2s1 2 and 1d3 2 cannot give reasonable result for the form factor.

The core-polarization effects are evaluated by adopting the shape of the Tassie-Model, together with the calculated ground Charge Density Distribution CDD for the low mass 2s-1d shell nuclei using the occupation number of the states where the sub-shell 2s is included with an occupation number of protons (α).
