Abstract :
The resonance recently observed by Fernández-Alonso et al. at a total energy of 1.83 eV for H+D2 (ν=j=0)→HD (ν′=3,j′=0)+D is analyzed in terms of a locally vibrationally adiabatic model. The resonance is assigned as a ν1=3, ν2=0 vibrational state of a D–DH complex with total angular momentum quantum numbers of about 20, and it is associated with a vibrationally adiabatic barrier at a D–D distance of 2.9 to 3.1 a0. The assignment explains the preferential decay into the ν′=3, j′=0 state of HD.
