Elastic Form Factors and Proton Momentum Distributions for Some fp- Shell Nuclei Using the Coherent Density Fluctuation Model

The ground state proton momentum distributions (PMD) and elastic charge form factors for some odd 1f-2p shell nuclei, such as , , 59 Co, 63 Cu and 65 Cu have been studied using 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 determined from the theory and experiment result. The feature of the long-tail behavior at high momentum region of the PMD has been calculated by both the theoretical and experimental fluctuation functions. It is found that the inclusion of the quadrupole form factors F cs(q)in all nuclei under study, which are described by the undeformed 1f-2p shell model, is necessary for obtaining a notable accord between the theoretical and experimental form factors.
