Fine-structure-changing collision cross sections within the low-lyingnD2states of rubidium induced by ground-state rubidium atoms Academic Article uri icon


  • The thermal cross sections for inelastic transfer of excited rubidium atoms from the n D522 to the n D322 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 10-14 cm2) for n being 5-9 are 2.90.6, 6.91.4, 11.52.3, 17.13.0, and 26.05.0, respectively. The fine-structure-changing cross sections are of the order of the geometrical cross sections and increase slightly less than (n*)4 for the low-lying n D2 states studied. 1984 The American Physical Society.
