摘要：

The photon energy differential shape of the second order matrix element for the two-photon (2E1) decay of the 1s2s(1)S(0) level in He-like gold has been measured. The results are in agreement with a recent fully relativistic calculation. The corresponding 2E1 matrix element deviates from those in lighter He-like systems due to the strong central field in a heavy two-electron ion. (C) 1999 Published by Elsevier Science B.V.
