Abstract:

In this paper we report energy and angular distributions of electrons emitted in collisions of protons with neon- (F-, Ne0, Na+), argon- (Cl-, Ar0, K+), krypton- (Br-, Kr0, Rb+), and xenon- (I-, Xe0) isoelectronic series for high and intermediate impact energies. Calculations were performed within the continuum distorted wave-eikonal initial-state method using an angular expansion in spherical harmonics and a numerical evaluation of the radial functions corresponding to both: the initial (bound) and the final (continuum) states in the same central potential. The first Born approximation was calculated on equal footing. The shellwise local plasma approximation was also calculated when possible. A complete and exhaustive comparison with the available experimental data is carried out. We have spanned almost all the published experiments in our range of interest. Successes and failures of the different theoretical methods are pointed out. Possible signatures of many-electron effects are noticed. © 2009 The American Physical Society.
