Refined Orthogonal Variation-Perturbation Continuum-Distorted-Wave Treatment of BZ+ + H(1s) → B(Z-1)+(n) + H+ at intermediate velocity for n, Z ≫ 1

Abstract

A recently developed refined orthogonal variational continuum distorted-wave treatment of charge transfer is applied to calculate cross sections for the process BZ+ + H(1s) → B(Z-1)+(n) + H+ at the intermediate velocity of 2 a.u. and where the projectile BZ+ is a fully stripped ion. Values are presented for Z ∊ [12, 18] and n ∊ [9, 16] and are compared to the recent experimental values of Hvelplund, Knudsen and collaborators for the collision AuZ+ + H2. It is concluded that for the parameters in question the refinements concerning orthogonalization of initial and final states and normalization of the initial state are indeed necessary and result in reduction factors of the order of four. It is also concluded that the principal outstanding refinement is given by explicit intermediate continuum states as given by the second Born variational continuum distorted wave treatment.
