Abstract

The FI signals of dense Rb atoms were observed, and the dependence of the decay rate on B₀, P and θ was obtained. Results were quantitatively interpreted as the intrinsic dynamics of highly polarized multilevel atoms under the influence of the spin-exchange interaction. The time evolution of atomic coherence was obtained by numerically integrating the nonlinear Liouville equation. The cross section of the spin-exchange collision was measured to be 3.5 × 10^-18 m^-2 by fitting the calculated dependence of the linewidth on B₀, P, θ, and N_RB.
