Reactive collisions between electrons and BeH above dissociation threshold.

Our previous studies of dissociative recombination and vibrational excitation/de-excitation of the BeH ion, based on the multichannel quantum defect theory, are extended to collision energies above the dissociation threshold, taking into account the vibrational continua of the BeH ion and, consequently, its dissociative excitation. We have also significantly increased the number of dissociative states of Π, Σ and Δ symmetry included in our cross section calculations, generating the most excited ones by using appropriate scaling laws. Our results are suitable for modeling the kinetics of BeH in edge fusion plasmas for collision energies up to 12 eV.
