We have observed optical nutation in cold <SUP>85</SUP>Rb atoms with a negligible Doppler broadening. The optical nutation of a two-level atom arranged by optical pumping has been studied as a function of detuning frequency and Rabi frequency. The change of the nutation signal caused by magnetic substate degeneracy has also been observed for &sigma; and &pi; excitations. This can be explained by optical nutation beatings from different transition probabilities among magnetic sublevels. Absolute transition probabilities with &sigma; and &pi; transitions and a branching ratio between them have been measured.
