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.
In a world increasingly facing new challenges at the forefront of plasma scientific research and technological innovation, CNR and ISTP pledge progress and achieve an impact in the integration of research into societal practices and policy
