Abstract	The results of an experimental study of population dynamics following excitation of 62D5/2, 3/2 and 82S1/2 states of rubidium are reported. Excitation transfer and quenching cross-sections in collisions with ground state rubidium atoms, and natural lifetimes have been measured. The experiment was performed in a vapour cell, using pulsed two-photon excitation and photon counting detection. The analysis of time dependent signals was based on a rate equation model in which transitions induced by thermal radiation have been accounted for. The measurements yielded following results: (1) 62D state J-mixing cross-section: σ 6D 5/2 Rb-Rb = 9.2(2.1) × 10−14 cm2; (2) cross-sections for 82S → 62D excitation transfer process: σ 8S→6D Rb-Rb = 3.4(1.2) × 10−14 cm2; (3) quenching cross-sections: σ q, 8S Rb-Rb = 12,8(3.4) × 10−14 cm2, σ q, 6D 3/2 Rb-Rb = 22.8(2.9) × 10−14 cm2, σ q, 6D5/2 Rb-Rb = 14.1(5.7) × 10−14 cm2; (4) radiative lifetimes: τ 8S = 161(3) ns, τ 6D 3/2 = 256(4) ns, τ 6D 5/2 = 249(5) ns.
