摘要：

Time-of-flight spectra of H(2S) and D(2S) fragments from electron-bombardment-dissociated H2, D2, and HD have been observed. Structure in the kinetic-energy distributions below 1.3 eV is interpreted as arising from predissociation of bound vibrational levels. For H2 and D2 the primary predissociation process appears to be predissociation of the D state via the B′ state. Predissociation structure for HD, although more prominent than for H2 and D2, is not as easily interpreted. Evidence for the direct dissociation of the B′ state has also been obtained and the relative probabilities of direct dissociation and predissociation have been estimated. © 1979 The American Physical Society.
