Abstract

Abstract : Zeeman quantum beats of helium Rydberg states were measured with synchrotron radiation. It is proposed that the polarization characteristic of extreme ultraviolet light can be simply evaluated by the measurement of the Zeeman quantum beats. Abstract : Quantum beats in fluorescence decay from Zeeman‐split magnetic sublevels have been measured for helium Rydberg states excited by synchrotron radiation. The Zeeman quantum beats observed in this prototypical case were fitted with an equation from a theoretical formulation. It is proposed that Zeeman quantum beat measurement can be a useful way to simply evaluate the polarization characteristics of extreme ultraviolet light.
