Charge form factor and cluster structure of the 6Li nucleus

Abstract

Abstract:The charge form factor of the 6 Li nucleus is considered on the basis of its cluster structure. The charge density of 6 Li is presented as a superposition of two terms. One of them is a folded density and the second one is a sum of the 4 He and deuteron densities. Using the available experimental data for 4 He and deuteron charge form factors, a satisfactory agreement of the calculations within the suggested scheme is obtained with the experimental data for the charge form factor of 6 Li, including those in the region of large transferred momenta.

Manifestation of Nuclear Clusterization in Coulomb Sums

“…The first-group nuclei are not clusterized, whereas the second-group nuclei are strongly clusterized. Thus, for the 6 Li nucleus, the parameter x varies between 0.3 and 0.4 [6,14,15], while for 7 Li we have x = 0.5 [14]. With this approach, we arrive the intersection of the lines determines the q p value.…”

“…at understanding of the intermediate (between the two groups) value q p = 1.65 fm −1 of the 12 C nucleus, because this nucleus is though clusterized but to a less degree than the nuclei of the lithium isotopes. For the 12 C nucleus, the parameter x ranges from 0.7 to 0.8 [14,15].…”

“…The first-group nuclei are not clusterized, whereas the second-group nuclei are strongly clusterized. For example, for the 6 Li nucleus, the parameter х varies between 0.3 and 0.4 [6,14,15], while for 7 Li we have х = 0.5 [14]. With this approach, we arrive at understanding of the intermediate value (between the two groups) q р = 1.65 fm -1 of the 12 С nucleus, which is clusterized substantially less than the nuclei of the lithium isotopes.…”
