Abstract

Experimental ratio for branching into the fine structure levels of the R_b5²P multiplet, as a consequence of an optical collision with A_r, is reported. An optically thin gaseous mixture of R_b and low-density A_r is excited by a cw dye laser. The excited R_bA_r molecule is dissociated into the R_b5P_1/2 or R_b5P_3/2, the branching ratio is defined as I(D₁)/I(D₂) where 1(D₁) and I(D₂) are measured intensities of the atomic R_bD₁ and D₂ lines. The branching is determined for tuning ranging from 600 nm to 570 nm and in the A_r density range 2 to 8 X 10¹⁷ cm^-3. The ratio of the dissociation rates and the fine structure changing cross section are obtained. The ratio of the dissociation rates approaches 0.7 as a limit which is independent of the laser frequency.
