Abstract
Vacuum ultraviolet laser-induced fluorescence (VUV LIF) method was emp loyed to study the angular relaxation of superthermal O(D-1) atoms by collision with Np molecules. 157-nm F-2 laser photolysis of O-2 to O(D -1) + O(P-3) channel channel was carried out to get O(D-1) atoms. And O(D-1) atoms were probed at 115.212 nm laser generated by frequency tr ipling technique. The angular relaxation rate constant of superthermal O(D-1) by collision with N-2 is measured to be 1.60 +/- 0.03 x 10(-10 ) cm(3) molecule(-1) s(-1).
