Radiative and relativistic effects in the decay of highly excited states in helium

• A recent experimental study [J.-E. Rubensson et al., Phys. Rev. Lett. 83, 947 (1999)] measured a significant fluorescence yield of the He(2lnl') photoexcited resonances, showing major qualitative differences from nonrelativistic predictions. We present a
