Stochastic Calculatlon of Interaction Energies

It is likely that the stabilization and golden rule procedure can be readily applied to vibrational Feshbach resonances as well. Eastes and Marcus have successfully used the stabilization method to locate such resonances in atom-diatom oscillator colinear collision^,^^ although they made no attempt to evaluate the resonance widths. Location of resonances by performing scattering calculations proved in the case (narrow resonances) treated in ref 35 to be very difficult. This again supports our belief that the present L2 method will be useful in supplementing conventional scattering techniques. Considering our results on the model two-open-channel problem as well as work of Winkler and Yaris31 it seems that the stabilization procedure provides a good starting point for a more efficient, less time-consuming version of 86, 12001204
