英文摘要Isotope shifts and total transition frequencies are calculated for the 2(2) S-3(2) S transition of the lithium isotopes Li-6, Li-7, Li-8, Li-9, and the halo nucleus Li-11. The accuracy is improved for previously calculated relativistic and quantum electrodynamic corrections, and in particular a disagreement for the Bethe logarithm is resolved for the ground S-2 state. Our previous result is confirmed for the 2(2) P state. We use the pseudostate expansion method to perform the sum over virtual intermediate states. Results for the second-order relativistic recoil term of order alpha(2)(mu/M)(2) Ry are shown to make a significant contribution relative to the theoretical uncertainty, but because of accidental cancellations the final result for the isotope shift is nearly unchanged. However, the spin-orbit term makes an unexpectedly large contribution to the splitting isotope shift (SIS) for the 2(2) P-1/2 - 2(2) P-3/2 fine structure, increasing the theoretical value for the Li-6 - Li-7 isotopes to 0.556 31(7) +/- 0.001 MHz. A comparison is made with high-precision measurements and other calculations for the SIS and for the total 2(2) S-3(2) S transition frequency.
