Rates are reported for transitions induced between the lowest excited 1, and 0: states of Xc2 by collisions with electrons and ground-state xenon atoms. Upper limits are established for the corresponding rates in argon, m the case of molecule-atom collisions. Resent interest in reactions involving electronically excited rare gas atoms and molecules has been motivated in part by attempts to explain the behavior of rare gas UV lasers, in particular the unexpected decreases in laser efficiencies at high pressures. Some have attributed this effect to phoroattenuation by the background gas [I], while others have suggested that it might result from mixing of the radiating 0: and 1, molecular states in collisions with either ground state atoms [2], or electrons [3]. This indicates the need for direct determinations of rates for the reactions Xez(l,,O,) + Xe kU 2 Xez (0:) + Xe (1) kd and Xe*,(l,,O,) f e-2 Xez(O+,) + ekb (2) and those for the corresponding reactions in the other rare gases.
