Table III. Individual contributions to the mass shift coefficient K (GHz · amu) for the 2 p$_{1}$$_{/}$$_{2}$ − 2 s and 2 p$_{3}$$_{/}$$_{2}$ − 2 s transitions in Li-like neodymium (Z=60). For middle- Z ions all parts are equally important. For high- Z region the QED and rela- tivistic contributions become dominant. It is interesting to note that for the high Z the QED contribution is larger than the relativistic one. One can see also that the relativistic contribution for the 2 p$_{3}$$_{/}$$_{2}$ − 2 s transition is much smaller than for the 2 p$_{1}$$_{/}$$_{2}$ − 2 s one. This is due to a large cancellation of the relativistic NMS and relativistic SMS contributions for the 2 p$_{3}$$_{/}$$_{2}$ − 2 s transition. We note also that for the 2 p$_{1}$$_{/}$$_{2}$ − 2 s transition the NMS equals to zero in hydrogenlike ions with a pointlike nucleus. The total results for the MS coefficient K for the 2 p$_{1}$$_{/}$$_{2}$ − 2 s and 2 p$_{3}$$_{/}$$_{2}$ − 2 s transitions in Li-like ions with the nuclear charge numbers Z = 3 − 92 are presented in Table V. Now the leading theoretical uncertainty for middle- and high- Z ions is determined by uncalculated electron-electron interaction effects of the QED recoil contribution. 9 Subset 2 p$_{1}$$_{/}$$_{2}$ − 2 s 2 p$_{3}$$_{/}$$_{2}$ − 2 s Ref.
