Charge exchange between bare beryllium and boron with metastable hydrogen atoms at low energies

Theoretical results for [sup 9]Be[sup 4+]-H(2[ital s]) and [sup 11]B[sup 5+]-H(2[ital s]) partial and total charge-exchange cross sections at low relative velocities (0.027--0.32 a.u.) are given, using the Landau-Zener method. The necessary molecular parameters for this method are obtained from the...

Description
Summary:Theoretical results for [sup 9]Be[sup 4+]-H(2[ital s]) and [sup 11]B[sup 5+]-H(2[ital s]) partial and total charge-exchange cross sections at low relative velocities (0.027--0.32 a.u.) are given, using the Landau-Zener method. The necessary molecular parameters for this method are obtained from the exact one-electron diatomic molecule (OEDM) molecular energies. The partial cross sections which are mainly populated are those corresponding to the principal quantum number of separated atoms [ital n]=5 for Be[sup 3+] and [ital n]=6 for B[sup 4+]. The total cross sections show a rather strong increase with increasing collision energies and a quite large maximum. They lie between the cross sections corresponding to the neighbor reactions for the incident nuclei with [ital Z]=3 (Li), [ital Z]=6 (C), and [ital Z]=7 (N). The atomic collisions with beryllium are very important in plasma tokamaks.
