Reactive collisions between electrons and BeT+.

In order to model and diagnose the low-temperature edge plasmas, a complete database for electron-impact collision processes is required for molecular species containing beryllium and hydrogen. Dominant elementary processes in cold ionized gases are dissociative recombination, elastic collisions, vibrational excitation, vibrational de-excitation and dissociative excitation. In this study, using the stepwise version of the Multichannel Quantum Defect Theory, cross sections and rate coefficients have been obtained for reactions induced on BeT⁺. A set of vibrational resolved rate coefficients for BeT⁺ cations' reactive collisions with electrons below to the ion dissociation threshold is provided. The incident electron energy range is 10-3 - 2.7 eV and the electron temperature range is 100 - 5000 K. [ABSTRACT FROM AUTHOR]
