摘要
Two-photon transitions in H-and He-like heavy ions in the presence of an external static electric field are explored using a relativistic Greens function approach and an independent particle model. The effects of Stark mixing on angular correlations, spectral distributions and total transition rates are analyzed in detail. Special emphasis is placed on the 2p(1/2) -> 1s(1/2) two-photon transition in H-like ions and the 1s(1/2)2p(1/2) : 2(3)P(0) -> 1s(1/2)(2) : 1(1)S(0) and 1s(1/2)2s(1/2) : 2(1)S(0) -> 1s(1/2)(2) : 1(1)S(0) two-photon transitions in He-like ions.
