 Willis Lamb, Jr., the Hydrogen Atom, and the Lamb Shift
Willis E. Lamb, Jr., was awarded the 2000 National Medal of Science for "his towering contributions to classical and quantum theories of laser radiation and quantum optics, and to the proper interpretation of non-relativistic quantum mechanics.
Lamb's discovery of the quantum effect that became known as the "Lamb shift" led physicists to rethink the basic concepts behind the application of quantum theory to electromagnetism.
Lamb continued working in the general area of atomic spectroscopy and theoretical laser physics as a member of the Stanford University faculty (1951-56) and as professor and Fellow of New College at the University of Oxford, England (1956-62).

 The Lamb Shift
In 1951, Willis Lamb discovered that this was not so - that the 2p(1/2) state is slightly lower than the 2s(1/2) state resulting in a slight shift of the corresponding spectral line (the Lamb shift).
While the Lamb shift is extremely small and difficult to measure as a splitting in the optical or uv spectral lines, it is possible to make use of transitions directly between the sublevels by going to other regions of the electromagnetic spectrum.
Willis Lamb made his measurements of the shift in the microwave region.

 Lamb shift - Wikipedia, the free encyclopedia
In physics, the Lamb shift, named after Willis Lamb, is a small difference in energy between two energy levels 2s
By using lower frequencies than for optical transitions the Doppler broadening could be neglected (Doppler broadening is proportional to the frequency).
This particular difference is a one-loop effect of quantum electrodynamics, and can be interpreted as the influence of virtual photons that have been emitted and re-absorbed by the atom.

 Physics Today January 2002
Lamb used this history to point out the perils of the temptation to treat evidence from a particularly reliable source with diminished weight because it deviates inconveniently from a well-established prevailing model.
I conclude that Houston is a half-forgotten hero of this story, the grandfather of the Lamb shift measurement (and a great uncle, maybe, of the QED revolution after Shelter Island).
Lamb must have had confidence from the beginning in just about what the result would be, and that confidence would have helped enormously in supporting the continuing determination needed for such a tour de force experiment.

Lamb joined the faculty of Columbia University in 1938 and worked in the radiation laboratory there during World War II.
Though the quantum mechanics of Paul A.M. Dirac had predicted the hyperfine structure of the lines that appear in the spectrum (dispersed light, as by a prism), Lamb applied new methods to measure the lines and in 1947 found their positions to be slightly different from what had been predicted.
While a professor of physics at Stanford University, California, (1951-56), Lamb devised microwave techniques for examining the hyperfine structure of the spectral lines of helium.

 Physics News Update Number 159 - NEW LAMB SHIFT MEASUREMENTS DISAGREE WITH QED   (Site not responding. Last check: 2007-10-21)
Ironically, QED was devised in the 1950s to explain the Lamb shift (named after Willis Lamb), the slight shift in the energy of an electron bound to a nucleus due to energy fluctuations in the vacuum, which can create electron-positron pairs or virtual photons seemingly out of nothing.
In what they have called "the most stringent test of QED for a bound atom to date," the researchers employed the latest advances in laser and optical spectroscopy to make the measurements of the 1S Lamb shift, which can be measured to greater precision than the 2S and 2P Lamb shifts traditionally studied.
However, the researchers do not particularly suspect that any "new physics" is at work here; they believe that a new, unpublished theoretical calculation taking into account previously ignored effects in QED should bring the results into agreement with theory.

 Re: how were the lamb shift experiments done?
Since the Lamb shift is so small (~1057 MHz), it is necessary to use very long wavelengths to observe this energy.
To measure the shift, he first had to excite atoms in the 2s(1/2) state hydrogen up to 2p(1/2) state because the atoms cannot directly transition from 2s(1/2) to 1s(1/2) due to
From the 2p(1/2) level, Lamb exposed the atoms to microwave radiation at 2395 MHz, then varied the magnetic field until it produced transitions from the 2p(1/2) to 2p(3/2) levels.
