Dissociative recombination of cold OH+: Evidence for indirect recombination through excited core Rydberg states.

Abstract

The dissociative recombination of ground state OH{sup +} ions with electrons has been measured, using the heavy-ion storage ring technique. A comparison of the cross section to recent theoretical results reveals that several observed resonances are due to a type of indirect dissociative recombination involving Rydberg states with a bound excited ion core. {copyright} {ital 1996 The American Physical Society.}
