Robert Hofstadter’s 1971 lecture is the second one relating to his new research field: total absorption detectors for gamma ray spectroscopy. His lecture follows upon the one by Paul Dirac, entitled “Fundamental Problems of Physics”, which sadly enough seems to be lost. Still, Hofstadter uses Dirac’s lecture to make a very good point, namely that to solve profound questions in physics ...
21. Mai 2018 · HOFSTADTER, Robert. ( b. 5 February 1915 in New York City; d. 17 November 1990 in Stanford, California), Stanford University physics professor who successfully applied atom-smashing technology to study the structure and size of nuclear particles. Hofstadter was the third of four children of Louis Hofstadter, a salesman, and Henrietta Koenigsberg.
Robert Hofstadter (n. 5 februarie 1915 , New York City , New York , SUA – d. 17 noiembrie 1990 , Stanford , Comitatul Santa Clara , California , SUA ) a fost un fizician evreu american , laureat al Premiului Nobel pentru Fizică 1961 „ pentru studiile sale de pionierat asupra împrăștierii electronilor pe nuclee atomice și pentru descoperirile sale astfel realizate cu privire la ...
Biographical Memoirs: Volume 79. Washington, DC: The National Academies Press. doi: 10.17226/10169. electron scattering from atoms and electron-nuclear scattering by Hanson, Lyman, and Scott at Illinois done at lower energies in 1951. Hofstadter showed that the nuclei had internal structure extending over a small but measurable distance and ...
Robert Hofstadter was awarded the National Medal of Science for his discovery and development of the sodium iodide scintillation counter leading to its application to spectroscopy in virtually all branches of science and technology, including imaging in medicine, and for his contributions to the understanding of the structure of elementary particles and atomic nuclei stemming from the ...
Abstract. Instead of an abstract, the text below is a short introduction by an editor. This is the last of four reports on Robert Hofstadter’s post-Nobel project: construction and operation of total absorption detectors for gamma ray spectroscopy. The earlier reports were given in 1968, 1971 and 1973. The title of this talk, “The Crystal ...
Robert Hofstadter. 1915-1990. American Physicist. C orecipient of the 1961 Nobel Prize in physics, Robert Hofstadter discovered that protons and neutrons are not indivisible particles, as was previously believed, but are complex components of the atom. He also developed the sodium iodide-thallium scintillator, a device for measuring radiation ...
