Abstract

Fragmentation dynamics of the HeBr₂(B, (nu) ) complex is studied by mens of three-dimensional quantum calculations for a broad range of vibrational excitations ((nu) ). Using additive pairwise potentials for both electronic states involved, X and B, resonance line shapes, lifetimes, average structures, spectral shifts and final product distributions are presented for an assumed main transition (X,J equals 1, j equals odd, parity equals negative) yields (B,J equals O,j equals even, parity equals positive). For (nu) equals 44, a partial closing of the (Delta) (nu) equals negative one channel of the fragmentation is found, in good agreement with the experiment.
