Abstract
Multichannel quantum defect theory is applied in the treatment of the dissociative recombination and vibrational excitation processes for the BeD + ion in the 24 vibrational levels of its ground electronic state (). Three electronic symmetries of BeD ∗∗ states (, , and ) are considered in the calculation of cross sections and the corresponding rate coefficients. The incident electron energy range is 10 -5 -2.7 eV and the electron temperature range is 100-5000 K. The vibrational dependence of these collisional processes is highlighted. The resulting data are useful in magnetic confinement fusion edge plasma modeling and spectroscopy, in devices with beryllium based main chamber materials, such as ITER and JET, and operating with the deuterium-tritium fuel mix. An extensive rate coefficients database is presented in graphical form and also by analytic fit functions whose parameters are tabulated in the supplementary material.
