โœฆ Synopsis

The thermally activated es~xpr rate of :! classical parrick OUI of a pownrinl nell is studied in 3 simple model u hlch includes coupling bctwecn the cscapc (reactive) coordmate and another coordinate. The main effect of the non-reactive coordinate is to open a neP' (non-markovian) channel betxecn the reactive coordinate and the thermal bath.

Deviations from the Kramers preditions resulting from the couplmg between a reactive and a non-reactwe mode are studied in both the low-and hi&-diction Iimits. It is alsO argued how this simple picture may provide a breakdown of the upper Iimit imposed on the relaxation rate by transdion state theor
