Inspecting State-Selective Distributions of Charge Exchange Cross Sections Due to Bare Ion Collisions with Hydrogen

  • M. S. Gravielle

摘要

State-selective electron capture cross sections due to collisions of multicharged bare ions—Li \(^{3+}\) , Be \(^{4+}\) , B \(^{5+}\) , C \(^{6+}\) , N \(^{7+}\) , and O \(^{8+}\) —with atomic hydrogen in its ground state are investigated within the eikonal impulse (EI) approximation. EI results for total and partial capture to final levels with main quantum numbers n ranging from 1 to 9 are analyzed considering impact energies from 25 to 1000 keV/amu. Furthermore, nl-selective cross sections for Be \(^{4+}\) projectiles are presented to illustrate the performance of the subshell electron distributions obtained with the EI method. In all the cases, the EI cross sections show a good agreement with available experimental and theoretical data in the intermediate and high-energy regions. Scaling laws for n-, nl-, and nlm-distributions, derived from the EI approach, are also discussed as useful tools to predict big atomic data sets for plasma and hadron-therapy applications.
