论文摘要
使用一种方法，使用一种方法，该方法纳入了碳，钙和氩气目标上的散射，该方法结合了来自Quasielastic（QE），非弹性过程以及两粒子和两孔中膜交换的电磁响应函数的贡献（$ 2P-2H $ MEC）。这种方法很好地描述了在截然不同的运动学下的全部能量谱。 It is shown that the accuracy of the $(e,e')$ cross section calculations in the region between the QE and delta-resonance peaks, where the $2p-2h$ MEC contribution reaches its maximum value, depends on the momentum transfer $|\q|$ and at $|\q|>500$ MeV the calculated and measured cross sections are in agreement within the experimental uncertainties.
The scattering of electrons on carbon, calcium, and argon targets are analyzed using an approach that incorporates the contributions to the electromagnetic response functions from the quasielastic (QE), inelastic processes, and two-particle and two-hole meson exchange current ($2p-2h$ MEC). This approach describes well the whole energy spectrum of data at very different kinematics. It is shown that the accuracy of the $(e,e')$ cross section calculations in the region between the QE and delta-resonance peaks, where the $2p-2h$ MEC contribution reaches its maximum value, depends on the momentum transfer $|\q|$ and at $|\q|>500$ MeV the calculated and measured cross sections are in agreement within the experimental uncertainties.
