Geometric phase and symmetry effects in dissociation dynamics of H3 — •Ulrich Galster and Jan-Michael Rost — Max-Planck-Institut für Physik komplexer Systeme, Dresden

Distinct structures have been observed in the distribution of breakup-geometries in three-body predissociation of Rydberg states of H3 [1]. Although a close relation to symmetry properties of the initial vibrational state and the involved non-adiabatic coupling is obvious, a detailed understanding of the formation of these structures is difficult to obtain. New insight in the dissociation process has been gained by means of quasi-classical simulations. They allow a comprehensible view on the formation of specific breakup-patterns under the influence of geometry-dependent non-adiabatic couplings and the evolution of nuclear configurations on the dissociative potential energy surfaces.
