What shift in electron energies in a hydrogen atom was discovered by Willis Lamb?

  • Lamb move

  • Lamb transformation

  • Lamb shift

  • Lamb twist

Answer

The Lamb shift is the difference between the energy levels of the 2S and 2P levels in the hydrogen atom, as calculated using the Dirac equation and as measured experimentally. It is named after Willis Lamb, who first observed it in 1947. The Lamb shift is due to the interaction of the electron with the vacuum fluctuations of the electromagnetic field.
