In the paper [], the case was considered in which an atom interacts with a plane monochromatic electromagnetic wave, and the optical equation with damping … WebbLamb-Retherford-Experiment 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 …

Lamb-Retherford experiment

WebbIt is shown that Lamb-Retherford experiment can be completely described within the framework of classical field theory without using such concepts as discrete states of the atom and jump-like electron transitions between them. The rate of stimulated decay of the metastable state of a hydrogen atom in an external periodic electric field is determined.

Lamb Shift - University of Washington

In 1947 Willis Lamb and Robert Retherford carried out an experiment using microwave techniques to stimulate radio-frequency transitions between S1/2 and P1/2 levels of hydrogen. By using lower frequencies than for optical transitions the Doppler broadening could be neglected (Doppler broadening … Visa mer In physics, the Lamb shift, named after Willis Lamb, is a difference in energy between two energy levels S1/2 and P1/2 (in term symbol notation) of the hydrogen atom which was not predicted by the Dirac equation, … Visa mer In 1978, on Lamb's 65th birthday, Freeman Dyson addressed him as follows: "Those years, when the Lamb shift was the central theme of physics, were golden years for all the physicists of my … Visa mer In 1947, Hans Bethe was the first to explain the Lamb shift in the hydrogen spectrum, and he thus laid the foundation for the modern development of quantum electrodynamics.
