Abstract

The nucleon momentum distributions ( NMD) for the ground state and elastic electron
scattering form factors have been calculated in the framework of the coherent fluctuation model
and expressed in terms of the weight function (fluctuation function). The weight function has been
related to the nucleon density distributions of nuclei and determined from theory and experiment.
The nucleon density distributions( NDD) is derived from a simple method based on the use of the
single particle wave functions of the harmonic oscillator potential and the occupation numbers of
the states. The feature of long-tail behavior at high momentum region of the NMD has been
obtained using both the theoretical and experimental weight functions. The observed electron
scattering form factors for Ne Mg 22 26 , and Si 30 nuclei are in reasonable agreement with the present
calculations throughout all values of momentum transfer q.
