Abstract
The nucleon-nucleon short-range correlation (NN-SRC) is one of the key issues of nuclear physics, which typically manifest themselves in high-momentum components of the nuclear momentum distributions. In this paper, the nuclear spectral functions based on the axially deformed relativistic mean-field model are developed to involve the NN-SRC. With the spectral functions, the inclusive electron scattering cross sections are calculated within the plane-wave impulse approximation (PWIA) framework, including the quasielastic (QE) part and production part. Especially in the production region, we reconsider the electromagnetic structures of the nucleon resonance (1232) and the scattering mechanisms, and thereby the theoretical calculations are improved effectively and the cross sections are well consistent with the experimental data. The theoretical cross sections are further divided into NN-SRC and mean-field contributions. It is found that, at the kinematics , the QE peak and production peak not only reflect the mean-field structure but also are sensitive to the NN-SRC information. Finally, we provide another method to extract the strengths of NN-SRC from experimental cross sections for selected nuclei at the suitable kinematics.
