Comment on “On the relation between unimolecular reaction rates and overlapping resonances” J. Chem. Phys. 101, 9672 (1994)

In a quantum mechanical many-body system at high level density different time scales are created by the trapping effect leading to a saturation of the average decay width of the narrow resonances. The trapping effect is a broadening of the distribution of the resonance widths, caused by the bifurcation of widths of neighboring resonances, which finally leads to a separation of the time scales. This saturation corresponds to that obtained by Peskin et al. for the decay rate. Thus, decay rate and average decay width behave in the same manner not only at low but also at high level density. The saturation should be proven experimentally by direct time measurements.
