Abstract

The magnetic-quadrupole transition

(1 s 2 p) 2^{3} P_{2} \to (1 s^{2}) 1^{1} S_{0}

of the heliumlike atom Ar XVII has been observed. A measurement of the lifetime of this state has been made by the beam-foil time-of-flight technique, with the result

τ (2^{3} P_{2}) = (1.7 \pm 0.3) \times 10^{- 9}
