摘要：
The 1s(2)2p(3/2)-1s(2)2s(1/2) x-ray transition in the Li-like Pb79+ has been observed using the Tokyo electron beam ion trap at the University of Electro-Communications. The contribution of QED (-24.99 +/- 0.10 eV) to the 1s(2)2p(3/2)-1s(2)2s(1/2) transition in Pb-208(79+) is determined and compared with different calculations. The measurement was made by calibrating the Pb line using the Lyman-alpha lines of the H-like S and the 1s4p P-1(1)-1s(2) S-1(0) transition in the He-like P.
