Paper Abstract

Experimental ratio for branching into the fine structure levels of the Rb52P multiplet, as a consequence of an optical collision with Ar, is reported. An optically thin gaseous mixture of Rb and low-density Ar is excited by a cw dye laser. The excited RbAr molecule is dissociated into the Rb5P1/2 or Rb5P3/2, the branching ratio is defined as I(D1)/I(D2) where 1(D1) and I(D2) are measured intensities of the atomic RbD1 and D2 lines. The branching is determined for tuning ranging from 600 nm to 570 nm and in the Ar 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.
