摘要：

We have measured two-photon decay of single K vacancies in gold atoms following photoionization with synchrotron radiation. Our results for the 2s-->1s and 3d-->1s two-photon transitions determine the rates for two-photon decay when the photons share the transition energy equally and have opening angles near theta=pi/2. These results are compared with nonrelativistic calculations for H-like Au ions and with theoretical and experimental results on lighter atoms.
