In physics, the Lamb shift, named after Willis Lamb, is an anomalous difference in energy between two electron orbitals in a hydrogen atom. The difference was not predicted by theory and it cannot be derived from the Dirac equation , which predicts identical energies.
Willis Eugene Lamb Jr. (/ l æ m /; July 12, 1913 – May 15, 2008) was an American physicist who won the Nobel Prize in Physics in 1955 "for his discoveries concerning the fine structure of the hydrogen spectrum."
Robert Curtis Retherford (1912–1981) was an American physicist.He was a graduate student of Willis Lamb at Columbia Radiation Laboratory.Retherford and Lamb performed the famous experiment (now known as the Lamb–Retherford experiment) revealing Lamb shift in the fine structure of hydrogen, a decisive experimental step toward a new understanding of quantum electrodynamics.

There he obtained his PhD with advisor Willis Lamb with a dissertation on measurement of the Lamb shift in singly ionized helium. [1] From 1953 to 1954 Lipworth held a fellowship with RCA. He also was a consultant at the Brookhaven National Laboratory and received research grants from the National Science Foundation. [2]
