Abstract

A metastable Ar beam was produced by electron impact with glow discharge. The Ar(³P_2,0) beam intensity was estimated to be ≈ 1 × 10¹⁴atoms sr^-1 s^-1'. Crossing this beam with a CF₃H beam, collision-free emission of CF₃ in the visible region was observed. The intensity maximum of the newly observed emission band of CF₃a was at 610 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 ≲ 1 A², i.e. 0.02 ± 0.01 in terms of the branching fraction for the Ar(³P_2,0) quenching.
