“…With the rapid development of the experiments, great efforts have also been devoted to the theoretical studies of electron scattering off nuclei in the last decade [27,28,29,30,31,32,33,34,35,36,37,38,39]. The plane-wave Born approximation (PWBA) is a simple method to solve the electron scattering where the effects of nuclear Coulomb field on the scattering electrons are neglected.…”
