Total transition probability and spontaneous radiative dissociation of B, C, B′ and D states of molecular hydrogen

The total radiative transition probabilities of rovibronic levels of B, C, B 0 and D states of molecular hydrogen are calculated with emphasis on the dissocia- tion fraction and the kinetic energy released in the con- tinuum radiation process. The mixing percentages of B, C, B 0 and D adiabatic states are also given. The data are calculated with the detailed transition probabilities ob- tained by Abgrall et al. (1993, 1994). We have included, in the present analysis, results obtained by using a recent ab initio transition moment for D X which comprises a larger range of internuclear distances. The related data on individual transition probabilities may be obtained on request.
