Effectiveness of projectile screening in single and multiple ionization of Ne by B2+

Abstract

Pure multiple ionization cross sections of Ne by B${}^{2+}$ projectiles have been measured in the energy range of 0.75 to 4.0 MeV and calculated using the continuum distorted wave-eikonal initial state approximation. The experiment and calculations show that the ionization cross sections by B${}^{2+}$, principally for the production of highly charged recoils, is strongly enhanced when compared to the bare projectile with the same charge state, He${}^{2+}$, at the same velocities.
