โœฆ Synopsis


A metastabie Ar beam was produced by electron impact with glow discharge. The A@P& beam intensity was estimated to be z I x 1 014 atoms sr-' s-'. Crossing this beam with a CF,H beam, collision-free emission of CF3 in the visible region was observed.

The intensity maximum of the newly observed emission band of CF, was at 6 10 nm, different from a previously reported value of 565 nm from a flowing afterglow experiment. The cross section of the visible emission of CF3 was 5 1 A', i.e. 0.02 3~ 0.01 in terms of the branching fraction for the AI$~P& quenching.

Chemiluminexence of the CQ radical formed in the reaction of Ar( 'P) with the oriented CFaH was taken at five different wavelengths in the range from 500 to 700 nm for two reactant orientations with a reference orientation. A remarkable alignment dependence of the emission spectra was observed. Anal
