Electron collsions with the interstellar molecular radicals CN, C 3N & C2H using the R-Matrix method

Abstract

Electron-molecule scattering calculations have been carried out using the UK Molecular R-Matrix codes on 3 neutral radicals observed in space, CN, C 3N & C2H. These calculations investigate the rates of formation of the relevant molecular anions in space. It was found that all scattering resonances are of too high energy for temporary resonance states to lead to anion formation. However weakly bound anionic states may provide a possible route to formation. © Published under licence by IOP Publishing Ltd.
