Abstract
A semiclassical approximation is used to investigate the plasma screening effects on electron-impact single ionization of helium-like ions in dense plasmas. The projectile-target interaction Hamiltonian is obtained by using an appropriate form of the non-spherical Debye-Huckel model. A semiclassical straight-line trajectory method is applied to the projectile path in order to visualize the ionization probability in dense plasmas as a function of the impact parameter and the Debye length. The final state of the ejected electron is represented by a plane wave solution normalized in the energy scale. For the initial state wave function, we use the independent particle model. The plasma screening effect on the ionization probability is appreciably increased with increasing projectile energy. The maximum position of the ionization probability recedes from the nucleus as the projectile energy increases.
