Rich reactive resonances are found in a 3D quantum dynamics study of the N + N-2 exchange reaction using our recently developed ab initio potential energy surface that has a shallow well between two transition states. An L-2 analysis confirms that the quasibound states of 'Lake Eyring' are responsible for the reactive resonances with some quasibound states, mostly the bending motions, giving rise to strong reasonance peaks, whereas others contributing to the shoulders in the resonance structure. This is the first observation of reactive resonances from a 'Lake Eyring' feature in a potential energy surface. (C) 2003 Elsevier B.V. All rights reserved.
