摘要
We present calculated total cross sections and product state distributions for the dissociative recombination of HeH+ with electrons in the high-energy resonance region. The dissociation dynamics were calculated by the solution of the time-dependent Schrodinger equation for seven coupled resonance states. The resonance curves and autoionization widths were obtained from a complex Kohn variational calculation. We compare several models for the nonadiabatic coupling. The effect of different isotopic combinations of the HeH+ ion on the total and partial cross sections is examined, and a prediction of the cross section for ion-pair formation is made.
