Lamb shift, fine structure constant and hyperfine structure in helium-like ions by fast-beam laser spectroscopy

Using Doppler tuned fast beam laser spectroscopy with a continuous wave CO2 laser the following energy intervals in helium like ions have been measured: 1s2s 1S0–1s2p 3P1,F, 3P0 in 14,15N5+; 1s2p 3P2,F–1s2p 3P1,F' in 19F7+; and 1s2p 3P0–1s2p 3P1 in 24Mg10+. The results test modern relativistic and QED atomic theory.
