Abstract:
A laser technique has been developed for the time-of-flight (TOF) analysis of state-selected atomic or molecular beams. The technique was applied to TOF measurements of Na atoms seeded in supersonic rare gas beams. When a dye Baser excited Na atoms in one of the hyperfine levels of the 3 2 S 1/2 state, this level was completely depopulated as a result of the optical pumping effect. This depopulation could be detected at a downstream position by the same Baser light, since the optically-pumped atoms were transparent, and thus the TOF spectrum could be derived by taking the time correlation between the pseudo-randomly modulated pump laser light and the depopulation detected by LIF. A preliminary scattering experiment of Na by CO 2 and SF 6 was carried out to confirm the effectiveness of this method.
