Dissociative Electron Attachment in Gas and Condensed Phases

Abstract

The resonance theory of electron-molecule collisions developed by O’Malley1 and Bardsley2 has become an efficient tool for ab initio calculations of dissociative attachment (DA) processes for diatomic molecules. However, theoretical calculations still cannot be performed routinely in the area of electron-atom and electron-molecule (nonreactive) collisions. Semiempirical methods are still widely used in studies of electron attachment to polyatomics. The resonance R-matrix theory3 is particularly useful for this purpose.
