The cross section for photoionization of excited cesium atoms has been measured in a triple crossed-beam experiment, i.e., two light beams crossing a beam of cesium atoms. The beam of exciting radiation was produced by a GaAs laser or by a cesium hollow cathode discharge lamp. The beam of ionizing radiation was produced by a 250 watt mercury arc lamp and dispersed by a 13 meter monochromator. The results show that the cross section as a function photon energy decreases faster than in the recombination measurements of Mohler and Boeckner. The report also includes separate articles on GaAs lasers, cesium masers, laser plasmas, and electron impact ionization, all related to the major photoionization program. Author
