Abstract:

The total radiative transition probabilities of rovibronic levels of B, C, B' and D states of molecular hydrogen are calculated with emphasis on the dissociation fraction and the kinetic energy released in the continuum radiation process. The mixing percentages of B, C, B' and D adiabatic states are also given. The data are calculated with the detailed transition probabilities obtained 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.
