[en] Studies concerned with the possible use of nuclear pumping to produce O₂(¹Δ) are described. The goal is to develop methods to produce adequate O₂(¹Δ) to use in an O₂-I₂ mixing-type laser. Although the O₂(¹Δ) concentrations generated in the nuclear induced discharge are too small for the operation of an iodine laser, one of the most promising approaches identified involves the initial production of ozone by nuclear pumping of a high pressure (approx. 5 atm) O₂-He mixture. The ozone mixture is then photodecomposed by use of a KrF nuclear pumped flashlamp. Based on a combination of experimental and theoretical data, it is estimated that O₂(¹Δ)/O₂ ratios > 0.3 can be produced this way with approx. 7 Torr of O₂(¹Δ) in a mixture initially containing 2 Torr of O₃. This is well above the minimum requirements for operation of an iodine laser. Experimental results of nuclear pumping O₂-noble gas mixtures in a pulsed TRIGA reactor are described and scaling relations developed
