Phys. Rev. A 67, 054501 (2003) [4 pages]Two-photon decay in gold atoms following photoionization with synchrotron radiationReceived 21 January 2003; published 22 May 2003 We have measured two-photon decay of single K vacancies in gold atoms following photoionization with synchrotron radiation. Our results for the 2s⃗1s and 3d⃗1s two-photon transitions determine the rates for two-photon decay when the photons share the transition energy equally and have opening angles near θ=π/2. These results are compared with nonrelativistic calculations for H-like Au ions and with theoretical and experimental results on lighter atoms. © 2003 The American Physical Society URL:
