Wiktionary
Lamb shiftnoun
A small difference in energy between two energy levels of the hydrogen atom in quantum electrodynamics, which can be interpreted as the influence of virtual photons that have been emitted and re-absorbed.
Etymology: Named after (1913-2008).
Wikipedia
Lamb shift
In physics, the Lamb shift, named after Willis Lamb, is a difference in energy between two energy levels 2S1/2 and 2P1/2 (in term symbol notation) of the hydrogen atom which was not predicted by the Dirac equation, according to which these states should have the same energy. Interaction between vacuum energy fluctuations and the hydrogen electron in these different orbitals is the cause of the Lamb shift, as was shown subsequent to its discovery. The Lamb shift has since played a significant role through vacuum energy fluctuations in theoretical prediction of Hawking radiation from black holes. This effect was first measured in 1947 in the Lamb–Retherford experiment on the hydrogen microwave spectrum and this measurement provided the stimulus for renormalization theory to handle the divergences. It was the harbinger of modern quantum electrodynamics developed by Julian Schwinger, Richard Feynman, Ernst Stueckelberg, Sin-Itiro Tomonaga and Freeman Dyson. Lamb won the Nobel Prize in Physics in 1955 for his discoveries related to the Lamb shift.

Lamb shift
In physics, the Lamb shift, named after Willis Lamb, is a small difference in energy between two energy levels ²S1/2 and ²P1/2 of the hydrogen atom in quantum electrodynamics. According to Dirac, the ²S1/2 and ²P1/2 orbitals should have the same energies. However, the interaction between the electron and the vacuum causes a tiny energy shift on ²S1/2. Lamb and Robert Retherford measured this shift in 1947, and this measurement provided the stimulus for renormalization theory to handle the divergences. It was the harbinger of modern quantum electrodynamics developed by Julian Schwinger, Richard Feynman, and Shinichiro Tomonaga. Lamb won the Nobel Prize in Physics in 1955 for his discoveries related to the Lamb shift.
