We present a coupled-cluster calculation for the electron-\(^4\)He scattering in the region of the quasi-elastic peak. We show the longitudinal and transverse responses separately, and discuss results within two distinct theoretical methods: the Lorentz integral transform and spectral functions. The comparison between them allows to investigate the role of final state interactions, two-body currents and relativistic effects.

耦合团簇理论中 $$^4$$ He 上的电子散射

我们提出了准弹性峰区域电子\(^4\) He 散射的耦合团簇计算。我们分别展示纵向和横向响应，并讨论两种不同理论方法的结果：洛伦兹积分变换和谱函数。它们之间的比较可以研究终态相互作用、二体电流和相对论效应的作用。
