Sažetak
In He-like systems the direct decay of the 1s2s 1S0 state to the 1s2 1S0 ground state is "forbidden". The transition 1s2s 1S0® 1s2 1S0 by two photons sensitively probes the structure of the complete atomic system. In particular, the shape of the two-photon spectrum is sensitive to it and also reveals for heavy atomic numbers details of relativistic effects in strong central fields. A brief survey on this field of research is given with special emphasis on high nuclear charge Z.
