Franck, James James Franck Bavaria-Verlag Nobel Prize for Physics in 1925 with Gustav Hertz for research on the excitation and ionization of atoms by electron bombardment that verified the quantized nature of energy transfer. Franck studied at the universities of Heidelberg and Berlin, received his doctorate from the latter in 1906, and served in the German army during World War I. He and Hertz performed their prizewinning work at the University of Berlin in 1912-14. They bombarded mercury atoms with electrons and traced the energy changes that resulted from the collisions. They found that electrons with insufficient velocity simply bounced off the mercury atoms, but that an electron with a higher velocity lost precisely 4.9 electronvolts of energy to an atom. If the electron had more than 4.9 volts of energy, the mercury atom still absorbed only that amount. The Franck-Hertz experiment gave proof of Niels Bohr's theory that an atom can absorb internal energy only in precise and definite amounts, or quanta. Franck's researches in the fields of photochemistry and atomic physics included determinations from molecular band spectra of the energy involved in the dissociation of molecules. During World War II he worked on the Manhattan Project, which developed the atomic bomb. Franck became a leader of those scientists in the Manhattan Project who sought to stop the bomb's use against Japan; they instead suggested that the bomb be exploded in an unpopulated area to demonstrate its power to the Japanese government.

James Franck (1882-1964) He was born in Germany and received the Nobel physics prize in 1925 with G. Hertz, for their experimental work on the behavior of free electrons in gases confirming some parts of Bohr's atomic theory. However, he resigned from the chair in Goettingen and moved to the United States after Hitler assumed power. During the World War II, he was working in the Metallurgical Laboratory of Chicago University, one of the centers for Manhattan Project; and toward the end of the War, he, together with several colleagues, submitted the "Franck Report" to the government, urging to avoid the use of the atomic bomb agaist Japan, and to prepare for the international control of the atomic power. Although the journalism usually praises Leo Szilard for his display of "conscientious and responsible" behavior, it seems that the Franck Report is the main source of all subsequent movements and discussions of the responsibility of the scientist.

Franck, James German-born US physicist. He shared a Nobel prize 1925 with his co-worker Gustav Hertz (1887-1975) for their experiments of 1914 on the energy transferred by colliding electrons to mercury atoms, showing that the transfer was governed by the rules of quantum theory. Investigating the collisions of electrons with rare-gas atoms, Franck found that they are almost completely elastic and that no kinetic energy is lost. With Hertz, he extended this work to other atoms. This led to the discovery that there are inelastic collisions in which energy is transferred in definite amounts. Franck also studied the formation, dissociation, vibration, and rotation of molecules, and was able to calculate the dissociation energies of molecules. Edward Condon (1902-1974) interpreted this method in terms of wave mechanics, and it has become known as the Franck-Condon principle.

Franck, James Americký fyzik nìmeckého pùvodu, který se v roce 1925 podìlil s Gustavem Hertzem o Nobelovu cenu za fyziku. Cenu dostali za výzkum v oblasti excitace a ionizace atomù pøi jejich ostøelování elektrony. Díky tomu také ovìøili kvantovou povahu pøemìn energie. Franck studoval na universitách v Heidelbergu a v Berlínì, kde v roce 1906 získal doktorát. Bìhem 1. svìtové války sloužil v nìmecké armádì. Spolu s Hertzem pracovali na objevech, za které dostali Nobelovu cenu, v letech 1912 až 1914 na Berlínské univerzitì. Vìdci sledovali pøemìny energie pøi srážkách atomù rtuti s elektrony, kterými tyto atomy ostøelovali. Objevili, že elektrony s nedostateènou kinetickou energií se od atomù jednoduše odrazí, zatímco elektrony s vyšší kinetickou energií pøi srážce pøedají atomu energii rovnu 4,9 eV. Pokud je kinetická energie elektronu mnohem vyšší než 4,9 eV, atom rtuti stejnì pohltí pouze energii 4,9 eV. Pokusy obou vìdcù dokazují Niels Bohrovu teorii, která øíká, že atom mùže pohlcovat energii pouze v pøesných, urèitých množstvích, tzv. kvantech.
