Rubidium vapour, together with a noble gas contained in a cell located in a 4.75T magnetic field, was irradiated with light from a pulsed dye laser. This radiation produced selective excitation of the 6$\sp{\rm z}$P$\sb{\rm J,m}$ (J = 1/2, 3/2, m = $-$3/2, $-$1/2, 1/2, 3/2) Zeeman substates. Collisions of the excited 6P atoms with He, Ne and Ar atoms and the resulting Zeeman mixing produced a population in the whole 6P Zeeman manifold and resulted in the emission of a Zeeman fluorescence spectrum which was resolved with a scanning Fabry-Perot interferometer, detected with a photomultiplier and stored in a multichannel scaler. The analysis of the fluorescence intensities of the components emitted in the decay of the directly (optically) excited state and of the collisionally populated states in relation to the noble gas densities, yielded the Zeeman mixing cross sections and the cross sections for the relaxation of dipole, quadrupole, and octupole moments.Dept. of Physics.
