Abstract

A precision measurement has been made of the lifetime of the

2^{3}

S_{1}

state of

{Xe}^{52 +}

by beam-foil time-of-flight spectroscopy. The result is τ

{(2}^{3}

S_{1}

)=2.554(76)×

10^{- 12}

sec, in agreement with theortical calculations. This measurement provides the most precise test of the theory of relativistic M1 decay and is sensitive for the first time to corrections of O(Zα

)^{2}

to the leading term.
