Absorption in the triatomic excimer, Xe2Cl

Abstract
The equilibrium internuclear geometry has been calculated for the excimer state of Xe2Cl. At this geometry absorption and emission transition probabilities have been calculated for transitions that bear on the gain of the Xe2Cl excimer transition and of the XeCl CA transition. The total lifetime of the Xe2Cl excimer state is found to be 330 ns for a fluorescence peak at 495 nm. Significant absorption is found to peak at 438 nm which would preclude tuning a laser over the entire fluorescence band. A very strong absorption from the Xe2Cl excimer state is also found at 339 nm which practically coincides with the broadband XeCl CA transition.
