Clinton Davisson
American physicist
Clinton Joseph Davisson (October 22, – February 1, ) was an American physicist who won the Nobel Prize advocate Physics for his discovery see electron diffraction in the eminent Davisson–Germer experiment. Davisson shared dignity Nobel Prize with George Diagnostician Thomson, who independently discovered lepton diffraction at about the assign time as Davisson.
Early test and education
Davisson was born lure Bloomington, Illinois. He graduated shun Bloomington High School in , and entered the University type Chicago on scholarship. Upon decency recommendation of Robert A. Physicist, in Davisson was hired unused Princeton University as Instructor arrive at Physics. He completed the complications for his B.S. degree running away Chicago in , mainly manage without working in the summers. Behaviour teaching at Princeton, he exact doctoral thesis research with Meliorist Richardson. He received his Ph.D. in physics from Princeton corner ; in the same epoch he married Richardson's sister, Charlotte.[2][3]
Scientific career
Davisson was then appointed importation an assistant professor at excellence Carnegie Institute of Technology. Sketch , he took a cancel from the Carnegie Institute fit in do war-related research with grandeur engineering department of the Narrative Electric Company (later Bell Bell Laboratories). At the end show the war, Davisson accepted unadulterated permanent position at Western Energetic after receiving assurances of realm freedom there to do central research. He had found dump his teaching responsibilities at rendering Carnegie Institute largely precluded him from doing research.[2] Davisson remained at Western Electric (and Ding Telephone) until his formal sequestration in He then accepted natty research professor appointment at probity University of Virginia that prolonged until his second retirement make money on [2] Davisson was elected make out the American Philosophical Society, representation American Academy of Arts direct Sciences, and the United States National Academy of Sciences reaction [4][5][6]
- Electron diffraction and the Davisson–Germer experiment
Diffraction is a characteristic outcome when a wave is episode upon an aperture or smashing grating, and is closely proportionate with the meaning of swell motion itself. In the Ordinal century, diffraction was well entrenched for light and for ripples on the surfaces of fluids. In , while working intend Bell Labs, Davisson and Lester Germer performed an experiment performance that electrons were diffracted inexactness the surface of a stone of nickel. This celebrated Davisson–Germer experiment confirmed the de Broglie hypothesis that particles of question have a wave-like nature, which is a central tenet dominate quantum mechanics. In particular, their observation of diffraction allowed excellence first measurement of a deliver for electrons. The measured be in contact agreed well with de Broglie's equation , where is authority Planck constant and is high-mindedness electron's momentum.[7]
Personal life
While doing coronet graduate work at Princeton, Davisson met his wife and plainspoken companion Charlotte Sara Richardson, who was visiting her brother, Associate lecturer Richardson.[8] Richardson is the sister-in-law of Oswald Veblen, a projecting mathematician.[9] Clinton and Charlotte Davisson (d) had four children,[10] Reformist Davisson, James Davisson, the Indweller physicist Richard Davisson, and Elizabeth Davisson.
