The thermal cross sections for inelastic transfer of excited rubidium atoms from the n /sup 2/D/sub 5/2/ to the n /sup 2/D/sub 3/2/ fine-structure state caused by fine-structure-changing collisions with ground-state rubidium atoms have been measured by selective stepwise excitation of the rubidium atoms and observation of the resulting fluorescence. The cross sections (in units of 10/sup -14/ cm/sup 2/) for n being 5--9 are 2.9 +- 0.6, 6.9 +- 1.4, 11.5 +- 2.3, 17.1 +- 3.0, and 26.0 +- 5.0, respectively. The fine-structure-changing cross sections are of the order of the geometrical cross sections and increase slightly less than (n()/sup 4/ for the low-lying n /sup 2/D states studied.
