| Abstract | ||
| The nucleon momentum distributions for the ground state and elastic electron scattering differential cross sections 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 feature of long-tail behavior at high momentum region of the nucleon momentum distributions has been obtained using both theoretical and experimental weight functions. An A-dependence of the nucleon momentum distributions has been clearly found in the region of high momentum component k 3 fm1. The observed differential cross sections for electron scattering from 20Ne, 24Mg, 28Si and 32S nuclei are very well reproduced by the present calculations throughout all values of scattering angle q. | ||
