Abstract: © 2018 Astro Ltd. In this paper, using the Landau-Dykhne formalism, we obtained an analytical formula for the transition rate in the tunneling regime with the inclusion of the electron-electron interaction and core excitation in a monochromatic elliptically polarized laser field. We focused on the simultaneous core ionization and core-excitation of helium (and helium-like) atom. Our theoretical results are shown to be highly sensitive to the ellipticity, parabolic coordinate and the laser field intensity. These parameters affect the transition rate intensity as illustrated by the obtained theoretical curves. The results were compared with other semi classical approaches.
