Feb. 1, 1958, Charlottesville, Va.), U.S. experimental physicist who shared the Nobel Prize for Physics in 1937 with George P. Thomson of England for discovering that electrons can be diffracted like light waves, thus verifying the thesis of Louis de Broglie that electrons behave both as waves and as particles. Davisson received his Ph.D. from Princeton University and spent most of his career at the Bell Telephone Laboratories. He began his research there on the emissions of electrons from a metal in the presence of heat and later helped develop the electron microscope. Then, in 1927, he and Lester H. Germer found that a beam of electrons, when reflected from a metallic crystal, shows diffraction patterns similar to those of X-rays and other electromagnetic waves. This discovery led to greater understanding of the dual nature of subatomic particles and proved to be useful in the study of nuclear, atomic, and molecular structure.

Extractions: Davisson, Clinton Joseph (1881-1958), an American physicist, shared the 1937 Nobel Prize in physics with British physicist George Paget Thomson. The two were recognized for their independent discoveries of the diffraction of electrons by crystals. Davisson was born in Bloomington, Illinois. He attended the University of Chicago on a scholarship but could not afford to continue beyond his first year. In January 1904, physicist Robert Andrews Millikan, his first physics instructor at Chicago, recommended Davisson for a position at Purdue University. In June 1904, Davisson returned to Chicago. When he again left for lack of funds, Millikan recommended him for a position at Princeton University. Davisson worked there until 1910. Studying in the summers, he graduated from the University of Chicago in 1908 and received his Ph.D. degree in 1911. Davisson and Charlotte Sara Richardson married on Aug. 4, 1911. They had four children. Davisson worked at the Carnegie Institute of Technology in Pittsburgh until 1917. During World War I (1914-1918), he joined the engineering department of the Western Electric Company in New York City. There he investigated the reflection of electrons from metal surfaces under electron bombardment in a vacuum. In a 1925 experiment, the accidental explosion of a vacuum tube caused a nickel target to become heavily oxidized. When Davisson removed the oxide from the target, he discovered that the angle of reflection of electrons had changed. Davisson later learned of the hypothesis of the wave nature of electrons proposed by French physicist Louis Victor de Broglie. Using de Broglie's theory, Davisson calculated the wavelength of the diffracted electrons. For his work, he shared the 1937 Nobel Prize in physics with British physicist George Thomson, who had made a similar discovery.

He attended the Bloomington public schools, and on graduation from High School in 1902 was granted a scholarschip by the University of Chicago for proficiency in mathematics and physics. In September of that year he entered the University of Chicago and came at once under the influence of Professor R.A. Millikan. Unable for financial reasons to continue at Chicago the following year he found employment with a telephone company in his home town. In January 1904 he was appointed assistant in physics at Purdue University on recommendation of Professor Millikan . He returned to Chicago in June 1904 and remained in residence at the University until August 1905. In September 1905, again on the recommendation of Professor Millikan, he was appointed part-time instructor in physics at Princeton University. This post he held until 1910, studying, as his duties permitted, under Professor Francis Magie, Professor E. P. Adams, Professor ( later Sir ) James Jeans and particularly under

Fisici fisico statunitense (Bloomington, Illinois, 1881-Charlottesville, Virginia, 1958). Insegnò fisica all'Istituto Carnegie di Tecnologia di Pittsburgh fino al 1917, quando passò ai laboratori della compagnia Bell di New York. Realizzò molte ricerche sull' effetto termoionico , sull' ottica e sulla fisica dei cristalli . Fondamentali furono i suoi lavori sulla diffrazione degli elettroni , in cui ebbe la collaborazione di L. H. Germer ; nel 1927 dimostrò che un fascio di elettroni incidenti su un cristallo di nichel subisce il fenomeno della diffrazione, dando così la prima conferma sperimentale dell'ipotesi formulata da L. de Broglie

Extractions: Felfedezte, hogy az elektronok a fényhullámhoz hasonlóan tudnak szétszóródni, és ez igazolja, hogy az elektronok hullámként és részecskeként is tudnak viselkedni. Pályafutásának nagy részét a Bell Telephone Laboratories-nál töltötte. Elõször a hõ hatására fémekbõl kilépõ elektronokat vizsgálta, majd az elektromikroszkóp megalkotásában vett részt. 1927-ben Davisson és Lester H. Germer felfedezték, hogy egy fémes kristályról visszaverõdõ elektronnyaláb a röntgensugárzáshoz és más elektromágneses hullámokhoz hasonló diffrakciós képet hoz létre. Ezzel a kísérlettel jobban meg lehetett érteni szubatomi részecskék kettõs természetét, és hasznosnak bizonyult az atommag, az atom- és molekulaszerkezet tanulmányozásában. Elismerései
