H. Dietz et V. Engel, Geminate recombination processes induced by rare gas collisions with predissociating NaI molecules prepared by femtosecond excitation, THEOR CH AC, 100(1-4), 1998, pp. 199-203
NaI molecules predissociate after excitation with ultrashort pulses at a pe
ak wavelength of 320 nm. In rare gas environments at higher pressures the p
rocess of geminate recombination is likely to occur. We studied the dynamic
s of these processes under various pressure conditions and for different co
llision partners. The calculations were performed within a three-dimensiona
l statistical model which simulates the NaI wave-packet dynamics with class
ical trajectories and the collisions via an instantaneous hard-sphere scatt
ering.
