摘要：

Predissociation of the short-lived 3(2)A'(2sa'(1)) state of D-3 and H-3 is studied by three-dimensional wave packet dynamics on the pair of coupled ground state potential energy surfaces. Momentum correlation diagrams for the three-body fragmentation via non-adiabatic transition to the unstable electronic ground state are calculated for the lowest eight vibrational levels (and J = 0). Compared to previous semiclassical methods, the agreement with experimental results is improved.
