Collisions of I-2 in the E electronic state with rare gas atoms result in electronic energy transfer to the D, beta, and D-' ion-pair electronic states. Rate constants for each of these channels have been measured when I-2 is initially prepared in the J=55, v=1 and 2 levels in the E state. The rate constants and effective hard sphere collision cross sections confirm the trends observed when v=0 in the E state is initially prepared: He collisions favor population of the D state, while Ar collisions favor population of the beta state. Final state vibrational level distributions are determined by spectral simulation and are found to be qualitatively consistent with the trends in the Franck-Condon factors. The experimental distributions are also compared to the recent quantum scattering calculations of Tscherbul and Buchachenko. (C) 2004 American Institute of Physics.
