Study of the EMC Effect for 27Al, 56Fe, 63Cu, and 107Ag Nuclei
ABSTRACT
In this paper the EMC effect for 27Al, 56Fe, 63Cu, and 107Ag nuclei are investigated with oscillator model. In this model has been assumed that nucleons in each level are affected by different mean field, so we use parameter having relation with radius of each level. Therefore; this assumption causes that extracted data for average binding energy
=-22.48MeV, =-23.79MeV, =-29.56MeV, and =-31.25MeVare considered for 27Al, 56Fe, 63Cu, and 107Ag nuclei, respectively. Achieving results have agreement with experimental data.
