摘要: Following (i) a sharp step or (ii) pulse of applied magnetic field, the resonance fluorescence an atomic vapour exposed to steady linearly polarized radiation undergoes transient behaviour until new state is reached; form will be modulation intensity with exponential envelope, simple decay. From period gJ value excited obtained. decay lifetime for relaxation alignment obtained directly. The technique, 63P1 mercury, gives 117.4+or-1.0 ns natural mean life.
