Elastic Electron Scattering from Some Even-Even Ge-Isotoes

A. Rahmani | F. Kaddoori

Abstract: The proton momentum distributions (PMD) and the elastic electron scattering form factors F (q) of the ground state for some even mass nuclei in the 2p-1f shell for 70Ge, 72Ge, 74Ge and 76Ge are calculated by using the Coherent Density Fluctuation Model (CDFM) and expressed in terms of the fluctuation function (weight function) |F (x) |2. The fluctuation function has been related to the charge density distribution (CDD) of the nuclei and determined from the theory and experiment. The difference of the CDD of ( -), ( -) and ( -) isotopes have been also calculated to illustrate the influence of the extra two neutrons on the CDD. The property of the long-tail behavior at high momentum region of the proton momentum distribution has been obtained by both the theoretical and experimental fluctuation functions. The calculated form factors F (q) of all nuclei under study are in good agreement with those of experimental data throughout all values of momentum transfer q.
