Recoil Correction to Hydrogen Energy Levels: A Revision
arXiv:physics/9706014 · doi:10.1134/1.558492
Abstract
Recent calculations of the order (Zα)^4(m/M)Ry pure recoil correction to hydrogen energy levels are critically revised. The origins of errors made in the previous works are elucidated. In the framework of a successive approach, we obtain the new result for the correction to S levels. It amounts to -16.4 kHz in the ground state and -1.9 kHz in the 2S state.
