A Calculation Method of Inclusive Electron Nucleus Quasi-elastic Scattering Cross Section at High Q²

The electron nucleus collision experiments are approaches measuring the structure of nuclei by using intermediate and high energy probe. This paper shows a calculation method of inclusive electron nucleus quasielastic scattering cross section at high Q² which based on a empirical formula of Nucleon-Nucleon Short Range Correlation (NN-SRC) and a model of electron deuteron quasi-elastic cross section in Weak-Binding Approximation (WBA). In WBA, the deuteron can be regarded as the combination of quasi-free proton and neutron and the short range correlation between them can be ignored. Therefore the structure function of deuteron can be written as the linear combination of that of proton and neutron, then one can get the cross section of deuteron. According to the cross section of deuteron and the empirical formula, one can obtain the cross section of nuclei A > 2 which considers NN-SRC effect. We compare our calculation results with existing experiments and the results calculated by Bosted' fit method, then find that our results match the experiments at high x and Q² > 2 GeV² and better significantly than the Bosted's results for some heavier nucleus, especially ⁴He.
