Frank, Ilya Mikhailovich


FRANK, ILYA MIKHAILOVICH (1908–1990), Russian Nobel laureate in physics. Frank, whose father was Jewish, was born in St. Petersburg (formerly Leningrad), graduated from Moscow State University in 1930, and received his doctorate in physico-mathematical sciences in 1935. He worked in the State Optical Institute in St. Petersburg (1931–34), followed by the P.N. Lebedev Institute of the U.S.S.R. Academy of Sciences. From 1941 he was in charge of the Atomic Nucleus Laboratory, becoming professor in 1944, and in 1957 he also became director of the Neutron Laboratory of the Joint Institute of Nuclear Investigations. He was a specialist in physical optics and his early interests concerned photoluminescence and photochemistry. He was awarded the Nobel Prize in 1958 (jointly with Pavel Alekseyevich Cherenkov and Igor Yevgenyevich Tamm) for his work on the Vavilov-Cherenkov effect, which concerns light emission by radioactive compounds. Solving the physical basis for this "glow" has had important applications in plasma physics, astrophysics, and radio wave generation. His later work concerned neutron physics.

Learn more about citation styles

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
