Electron driven reactive processes involving H\(^+_2\) and HD\(^+\) molecular cations in the Early Universe

We describe the major low-energy electron-impact processes involving H\(^+_2\) and HD\(^+\), relevant for the astrochemistry of the early Universe: Dissociative recombination, elastic, inelastic and superelastic scattering. We report cross sections and Maxwellian rate coefficients of both rotational...

Description
Summary:We describe the major low-energy electron-impact processes involving H\(^+_2\) and HD\(^+\), relevant for the astrochemistry of the early Universe: Dissociative recombination, elastic, inelastic and superelastic scattering. We report cross sections and Maxwellian rate coefficients of both rotational and vibrational transitions, and outline several important features, like isotopic, rotational and resonant effects.
