# Nature of the Darwin term and (Zα)4m3/M2 contribution to the Lamb shift for an arbitrary spin of the nucleus

@article{Khriplovich1996NatureOT, title={Nature of the Darwin term and (Z$\alpha$)4m3/M2 contribution to the Lamb shift for an arbitrary spin of the nucleus}, author={Iosif B. Khriplovich and A. I. Milstein and R. A. Sen'kov}, journal={Journal of Experimental and Theoretical Physics}, year={1996}, volume={84}, pages={1054-1057} }

The contact Darwin term is demonstrated to be of the same origin as the spin-orbit interaction. The (Zα)4m3/M2 correction for the Lamb shift, generated by the Darwin term is found for an arbitrary nonvanishing spin of the nucleus, both half-integer and integer. There is also a contribution of the same nature to the nuclear quadrupole moment.
