Detection of Excited States by Laser-Induced Fluorescence.

Abstract

Laser absorption techniques have been used to measure the collisional quenching rate coefficients for a number of levels of the hydrogen state. These rate coefficients are nearly independent of rotational and vibrational quantum number, i.e., 1.7 2.0 x ten to the negative fifteen cubic meter/s. Techniques are being developed for the measurement of electron excitation coefficients for the H2 state. Results are presented from attempts to model experimental measurements of 634 nm emission produced in collisions of pairs of oxygen metastables in the afterglow of pulsed discharges in Oxygen-Argon mixtures. Keywords: Hydrogen, Oxygen, Argon, Metastables, Electrons, Radiation, Excitation coefficient, Excited states.
