Abstract
The proton momentum distributions (PMD) and the elasticelectron scattering form factors F(q) of the ground state for someeven mass nuclei in the 2p-1f shell for 70Ge, 72Ge, 74Ge and 76Ge arecalculated 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 chargedensity distribution (CDD) of the nuclei and determined from thetheory and experiment. The property of the long-tail behavior at highmomentum region of the proton momentum distribution has beenobtained by both the theoretical and experimental fluctuationfunctions. The calculated form factors F (q) of all nuclei under studyare in good agreement with those of experimental data throughout allvalues of momentum transfer q.

Summary
The study of momentum distribution is important tool for studying the ground state properties of nuclei, especially the momentum distribution of protons [1]. This is measured in the framework of the coherent density fluctuation model (CDFM), which is exemplified by the work of Antonov et al [2, 3]. There is no method for directly measuring the proton momentum distribution PMD in nuclei. The experimental evidence obtained from inclusive and exclusive electron scattering on nuclei establish the existence of long- tail behavior of the PMD at high momentum region (k ≥ 2 fm-1) [4,5,6].
