We present a comprehensive analysis of existing measurements of the ls2s 3SIl s2p 3Po.!. 2 transition energies in heliumlike ions for nuclear charges Z=2 to Z=92. We find agreement with the standard unified calculations of IDrake except for the transitions from the l s2p 3P0 state. We find a deviation equal to 2.3x(Z/10) 4 cm "1 for the most precise existing measuremems. | by e contractor Of the U.S. Government J under contract No. W-31.109-ENG-38. | Accordingly, the U. S.
