Experimental and theoretical x-ray transition energies are precisely estimated and compared for 40<Z<100. All allowed and forbidden intervals for the n=1 to n=2, 3 levels are determined. The experimental values are derived from absolute wavelength measurements of Kα and Kβ transitions and from L series x-ray measurements. The theoretical values are obtained using a multiconfiguration Dirac-Fock code with some modifications in the Lamb shift calculations. Comparison between experiment and theory for Z<85 now provides a more coherent qualitative picture : (1) for the 1s-1→2s-1, 1s-1→3s-1, and 1s-1→3p-1 transitions, experimental energies are 5-10 eV larger, consistent with the magnitude and sign of the level shifts resulting from pair correlat...
