Eikonal calculation of electron-capture cross sections in collisions of H atoms with fast projectiles

Journal Article · · Phys. Rev. A; (United States)
; ;
We have employed the eikonal method to calculate the cross section for the capture of an electron into an arbitrary nl subshell in collisions between hydrogen atoms and fast projectiles. the projectiles were protons, C/sup 6 +/, O/sup 8 +/, and Fe/sup 24 +/. The energy ranges considered were 20--100 keV in the proton case, and 40--200 keV per nucleon in the other cases. These projectiles were selected because of their importance in fusion plasmas. For the highly charged case of Fe/sup 24 +/ we found that our formulas, while exact, involved a high degree of cancellation and produced unreliable numerical results, so that a numerical integration of the penultimate formula was substituted. In the proton case agreement with recent experimental data is excellent.
