Abstract

Using ultrafast laser excitation and time-correlated single-photon counting techniques, we have measured the collisional mixing rates between the rubidium 5 2 P fine-structure levels in the presence of He 4 gas. A nonlinear dependence of the mixing rate with He 4 density is observed. We find Rb fine-structure transfer is primarily due to binary collisions at He 4 densities of 10 19 cm 3 , while at greater densities, three-body collisions become significant. We determine a three-body collisional transfer rate coefficient ( 5 2 P 3 / 2 5 2 P 1 / 2 ) of 1.25 ( 9 ) × 10 32 cm 6 / s at 22 ° C .
