Fine Structure of the Hydrogen Atom by a Microwave Method(95 views)
Description: FIRST EDITION IN ORIGINAL WRAPPERS of the discovery of the "Lamb shift". ?Shortly after World War II, Lamb began his work to check the accuracy of the predictions of Paul Dirac as they related to the energy levels and spectral lines of hydrogen. Dirac?s quantum mechanical theory predicted that the hydrogen atom had two possible energy states with equal energies. Lamb?s accurate work using radiofrequency resonance techniques, reported in 1947, revealed that there was a minute difference in these energy levels. Small as it was, this Lamb shift necessitated a revision of the theory of the interaction of the electron with electromagnetic radiation. For this work Lamb was awarded the Nobel Prize for physics, which he shared with another leader of research at Columbia, Polykarp Kusch, with whom he had performed wartime research in developing microwave radar?
