<Clinton Davisson> and <Lester Germer> measured strong angular structure in <electron> scattering from a <nickel> <crystal>. Its dependence on incident <electron> <energy> agreed with a <wavelength> set by the <electron> <momentum> through the <de Broglie wavelength>. The <crystal> therefore supplied a periodic structure against which <electron> wave behavior could be tested. The <Davisson–Germer experiment> linked a tunable <electron> source and angularly resolved detector with the theoretical idea of <matter waves>.<Diffraction of Electrons by a Crystal of Nickel by C. Davisson and L. H. Germer>[Physical Review 30, 705 (1927), energy/angular diffraction measurements]{ref}
A <physicist> whose route into research included a telephone-company job when he could not afford to continue at Chicago. He later worked at Bell Telephone Laboratories, retiring in 1946 after 29 years, and taught <physics> at Virginia in 1947–1949.<Clinton Davisson – Biographical>[Biography: financial interruption, laboratory employment and visiting professorship]{ref} The <Davisson–Germer experiment> connects that industrial-laboratory work to <electron diffraction> and <matter waves>.
