New extended method for ?' scaling function of inclusive electron scattering

Scaling analyses have been successfully applied to study the inclusive electron scattering (e, e & PRIME;) over the past few decades. In this study, we utilize the & psi;& PRIME; scaling function in momentum space to analyze the (e, e & PRIME;) cross sections, where the nucleon momentum distributions are derived from self-consistent mean-field calculations. By further introducing the energy and momentum conservation in the scaling analysis, an improved & psi;& PRIME; scaling function is proposed to investigate the high-momentum part of the momentum distributions. Using the proposed scaling function, we systematically explore the effects of the nucleon-nucleon short-range correlation (NN-SRC) on the (e, e & PRIME;) cross sections. From the experimental (e, e & PRIME;) data, the NN-SRC strength is further extracted within the framework of the improved & psi;& PRIME; scaling function. The studies in this paper offer a new method to investigate the nucleon momentum distributions and the NN-SRC effects in nuclei.
