Abstract

The lifetime of the

{}^{3}P_{1}

state of Sr has been measured by observing the intensity of the

5 s^{2} {}^{1}S_{0} \leftrightarrow 5 s 5 p {}^{3}P_{1}

fluorescence as a function of time, following the excitation of the

{}^{3}P_{1}

state by a 1-μsec pulse from a flashlamppumped dye laser. The measured value of the

{}^{3}P_{1}

lifetime is 21 ± 1 μsec.
