Abstract
We present in this paper MQDT calculations of the dissociative recombination process of H2+, HeH+ and LiH+ with very slow electrons. The process is induced by non-adiabatic interactions. Based on a recently derived (Stolyarov and Child 2001 Phys. Rev. A 63 052510) generalised Hellman–Feynman theorem, regular radial coupling effects can be treated explicitly. Our treatment uses a bound-continuum electronic matrix of the radial coupling between a Rydberg dissociative state and the lε electronic continuum with the same lλ to calculate the cross sections for the dissociative recombination.
