  • Abstract
    The emission from the transition I*(52 P_{1/2}) \\rightarrow I(52 P_{3/2} ) at 1.315 μm following injection of HI into a microwave-discharged He/O2flow has been studied. Relative I*(52 P_{1/2} ) emission intensities have been recorded as a function of HI and O2flow rates and as a function of time after injection. Pulsed gain measurements using an iodine photodissociation laser as a source show that the ratio, N_{I}*/ (N_{I} +N_{I}*,) \\approx 0.15-0.25 , is less than that required for population inversion. This observation will be discussed in terms of known chemical processes involving O(3 P ), HI, O2(1Δg), and iodine atoms.
