Abstract

Cross sections for mutual neutralization processes in magnesium-deuterium collisions are calculated in the collision energy range 0.001–100 eV by the probability current method. Special attention is given to the collision energies in the vicinity of Ecol = 0.059 eV. Partial rate coefficients for mutual neutralization processes are calculated at the temperature T = 6000 K and compared with previous experimental and theoretical results. It is shown that the present data agree reasonably with the previous results.
