Collisional relaxation of 2S–nS and 2S–nD superposition states in atomic Li vapor is measured with the trilevel photon-echo technique. Principal quantum numbers range from n = 4 to well into the Rydberg regime with n = 30. For the rare-gas perturbers (He, Ne, Ar, Kr, and Xe) the variation of collisional cross section with n is considerably weaker than that previously found with Na vapor.

Collisional relaxation of 2S‐nS and 2S‐nD superposition states in atomic Li vapor is measured with the trilevel photon echo technique for principal quantum numbers range from n=4 to well into the Rydberg regime (n=30). With noble gas perturbers (He, Ne, Ar, Kr, and Xe) the variation of collision cross section with n is considerable weaker than previously found for Na vapor.
