Elastic Electron Scattering from 35Cl, 37Cl and 39K Nuclei

The ground state proton momentum distributions and elastic charge form factors for some odd 2s-1d shell nuclei, such as 35Cl, 37Cl and 39K nuclei have been studied utilizing the Coherent Density Fluctuation Model and formulated by means of the fluctuation function (weight function) |f (x) |2. The fluctuation function has been connected to the charge density distribution of the nuclei and obtained from the theory and experiment. The feature of the long-tail behavior at high momentum region of the PMD has been determined by both the theoretical and experimental fluctuation functions. It is found that the inclusion of the quadrupole form factors Fc2 (q) in all nuclei under study, which are described by the undeformed 2s-1d shell model, is essential for obtaining a notable accord between the theoretical and experimental form factors.
