- Abstract
Inelastic processes in the low-energy collisions Li + H, Li + H, Li + H and Li + H are investigated for all collisional channels with the excited ionic lithium states Li ( nl) and Li (1 s nl) up to and including the corresponding ion-pair states for the temperature range 1000-20 000 K. For all possible processes in the Li + H and Li + H collisions inelastic cross sections and rate coefficients are calculated for the transitions between the ion-pair channel Li + H and the 35 below lying contributing Li ( nl) + H channels. It is found that the highest values of cross sections and rate coefficients are obtained for the recombination processes and their inverse, the ion-pair formation processes, involving the Li (3 l), Li (4 l), and Li (5 l) states. For the processes in the Li + H and Li + H collisions, cross sections and rate coefficients are calculated for all transitions between 34 Li (1 s nl) + H channels lying below Li + H plus this ion-pair channel. In this case the highest rate coefficients correspond to the recombination processes with the Li(1 s3 l L) and Li(1 s4 l L) final states, as well as their inverse processes of ion-pair production. Rate coefficient values for these most efficient processes are rather high, of the order of 10 cm/s. This leads to total recombination rate coefficients in Li + H and Li + H collisions with values larger than 10 cm/s. Graphical abstract:
