Sep 1, 2002 · In 1927 Clinton Davisson and Lester Germer observed the diffraction of electron beams from a nickel crystal – demonstrating the wave-like properties of particles ...
Clinton Joseph Davisson was born in Bloomington, Illinois, USA on October 22, 1881, just four days before the notorious gunfight at the O.K. Corral in Tombstone, Arizona. His father was Joseph Davisson, a housepainter who had once fought in the Union Army. His mother, Mary Calvert, was a school teacher. Clinton had a younger sister Carrie, born ...
Germer, Lester Halbert, 1896-Worked together on the Davisson-Germer experiment, which confirmed the de Broglie hypothesis. Thomson, G. P. (George Paget), 1892-1975. Shared the 1937 Nobel Prize in Physics "for their experimental discovery of the diffraction of electrons by crystals." Thomson, J. J. (Joseph John), 1856-1940
Physics questions and answers. A series of experiments by Clinton Davisson and Lester Germer in the 1920s gave a clear indication of the wave nature of matter. The investigators scattered a relatively low energy electron beam from a nickel crystal. They found very strong reflections at certain angles that varied with the energy of the electron ...
Proving the wave nature of matter through the experimental discovery of the diffraction of electrons by crystals.
The intensity of scattering of a homogeneous beam of electrons of adjustable speed incident upon a single crystal of nickel has been measured as a function of direction. The crystal is cut parallel to a set of its {111}-planes and bombardment is at normal incidence. The distribution in latitude and azimuth has been determined for such scattered electrons as have lost little or none of their ...
Sep 10, 2020 · The first experiment, proposed by Clinton Davisson and Lester Germer in 1927, was based on a hypothesis put forth earlier by Louis de Broglie in 1922. De Broglie suggested that if waves (photons) could behave as particles, as demonstrated by the photoelectric effect, then the converse, namely that particles could behave as waves, should be true.
