Determination of hyperfine structure and gjfactors in the sequences of2D states in alkali atoms using a tunable dye laser

Abstract

We have extended recently reported hyperfine structure studies of 2D states in alkali atoms to several new states. The 2D states were populated in a two-step excitation scheme, involving a conventional RF lamp and a cw tunable dye laser. Using level crossing and optical double resonance techniques we have determined the hyperfine structure of the 8 2D3/2,5/a states in 8TRb and the 11, 12, 13, 14 aD3/a,5/a states in 133Cs. Further, g, factors for several of these states were determined.
