Relativistic random-phase approximation longitudinal response functions for quasielastic electron scattering with nonlinear models

Abstract

The longitudinal response functions for quasielastic electron scattering on ${}^{12}\mathrm{C},$ ${}^{40}\mathrm{Ca},$ and ${}^{56}\mathrm{Fe}$ have been calculated taking into account relativistic RPA correlations. For these calculations relativistic nonlinear models, providing a good description of ground state properties of finite nuclei, have been used. The effect of the nonlinear terms on the longitudinal response has been discussed.
