Abstract
We report measurements of lifetimes of the Rb(n(2)F) (n = 6, 7, 8) sta tes performed in a vapour cell. The F-states were excited in a two-ste p sequence of an electric-dipole transition followed by an electric-qu adrupole transition. Single photon counting was used for detection. Th e results are: tau(6(2)F)=171(4), tau(7(2)F)=262(15), tau(8(2)F) = 387 (12) (in ns). These lifetimes, have been compared with theoretical val ues given by different authors. An estimate of the cross sections for quenching due to collisions with ground-state Rb atoms is also given.
