Abstract: 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. Our results are suitable for modeling the kinetics of BeH⁺ in edge fusion plasmas for collision energies up to 12 eV.
