摘要:
Scaling analyses have been successfully applied to study the inclusive electron scattering (e, e′) over the past few decades. In this study, we utilize the ψ′ scaling function in momentum space to analyze the (e, e′) 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 ψ′ 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′) cross sections. From the experimental (e, e′) data, the NN-SRC strength is further extracted within the framework of the improved ψ′ scaling function. The studies in this paper offer a new method to investigate the nucleon momentum distributions and the NN-SRC effects in nuclei.
