摘要
报道铥(Tm)原子10个中等能量激发能级自然辐射寿命的实验测量值.采用两台脉冲染料激光器将铥原子从基态激发到待测能级,再从铥原子激发态所释放的荧光随时间衰变的规律推算出自然辐射寿命值.测量精确度为10％.
Lifetime measurements on Tm atoms have been performed with two-step laser excitation and observing the time-resolved fluorescence released from the excited states to be .measured. Ten lifetime values of neutral Tm atoms are first reported.
