Nuclear Beta Decay

Up to now we have developed the theory of the weak nuclear interaction at the level of the quarks, that is to say, of the constituents of the hadrons. In order to describe the weak interactions of the hadrons themselves we must in addition know how the hadrons are made up of quarks, that is, we must know the wave functions of the quarks within the hadrons. This problem has not yet been completely solved, but there are a number of models which reflect some properties of the hadrons quite well.

Bibliographical Notes

  1. BETHE, Hans Albrecht, physicist, *2.7.1906 in Strasbourg, professor at Cornell University in Ithaca (New York). He was educated at the universities of Frankfurt and Munich, obtaining his Ph.D. in 1928 under Sommerfeld. He worked under Rutherford in Cambridge and Fermi at Rome, then taught physics at Munich and Tübingen until 1933, when he emigrated to England and later to the United States. Bethe's main contribution to science was working out the details of the nuclear mechanisms that power the stars, which he achieved in 1938, when Weizsäcker was independently reaching similar conclusions in Germany. He also contributed to the development of quantum electrodynamics, and was the first to calculate the Lamb shift in hydrogen. In 1967 he received the Nobel Prize for physics.Google Scholar
  2. YOUNGMAJORANA, Ettore, *5.8.1906 in Catania (Italy), dropped out of sight in 1938, went to the classical secondary school of Catania until the final examination in 1923. Afterwards he studied engineering sciences in Rome until the last year of studies. 1928 transfer to the physics faculty and 1929 Ph.D. in theoretical physics under Fermi. Title of the thesis: “Quantum Theory of Radioactive Atomic Nuclei”. In the subsequent years freelance collaborator at the Institute of Physics in Rome. In 1933 he went to Germany (Leipzig) for some years and worked with Heisenberg. This resulted in a publication on nuclear theory (Z. Phys. 82, 137 (1933)). In 1937 he published “The Symmetric Theory of Electron and Positron” and four years after his disappearence the “Significance of Statistical Laws for Physics and Social Sciences” was published.Google Scholar
