The purpose of this work is to discuss the utility of electron scattering in the study of nuclear properties. The Nucleon Momentum Distributions (NMD) and elastic electron scattering form factors of the ground state for 1p-shell nuclei have been calculated in the framework of the Coherent Density Fluctuation Model (CDFM) and expressed in terms of the weight function. The feature of the long-tail behavior at high momentum region of the NMD has been obtained by both the theoretical and experimental weight functions on contrary to the results of the NMD calculated in the shell model by taking...
