Transient absorption experiments in pure and mixed rare gases were performed at the XeF laser wavelength using a broadband probe technique. The major absorbing species in this region are identified. There is a strong broadband absorption in electron-beam-excited argon which is due to Ar/sup +//sub 2/. In neon plasmas the broadband absorption is much weaker. However, there are a number of strong line absorptions due to Ne(3s-4p) transitions, one of which coincides with the 351-nm emission band of the XeF laser. Addition of xenon reduces Ne* absorption. The amount of xenon used is limited by the formation of Xe/sup +//sub 2/, which is also a strong absorber in the 350-nm region.
