James Franck. geb. 1882 in Hamburg. gest. 1964 in Göttingen. Gustav Hertz. geb. 1887 in Hamburg. gest. 1975 in Ostberlin. Um 1914 (also ein Jahr nachdem Bohr sein Modell formuliert hatte) beschäftigten sich viele Physiker mit Gasentladungen (In ein Gas - meist mit Unterdruck - werden zwei Elektroden eingebracht, an die eine Spannung angelegt ...
About James Franck James Franck was born on August 26th 1882 in Hamburg, Germany as the second child to the Jewish banker Jacob Franck and his wife, Rebecka Decker.

10. Sept. 2014 · In 1911, James Franck and Gustav Hertz began a collaboration to investigate the nature of collisions of slow electrons with gas molecules that led to a series of carefully planned and executed experiments, culminating in their discovery of inelastic collisions of electrons with mercury vapor atoms in 1914. This paper tells the story of their collaboration and the eventual reinterpretation of ...
18. Juli 2014 · Abstract. The 1914 experiment of James Franck and Gustav Hertz provided a graphic demonstration of quantization properties of atoms, thereby laying the foundations of modern atomic physics. This article revisits the experiment on the occasion of its Centenary, compares traditional and modern interpretations, and focuses in particular on the ...
In 1926, James Franck went to Stockholm to receive the 1925 Nobel Prize in physics, which he shared with Gustav Hertz for their experiments supporting Neil Bohr's theory of the atom. He then began to investigate absorption spectra of alkali halides with Heinrich Kuhn and Günter Rollefson. Franck, Born, and Pohl founded a regional branch of the ...

The Invisible Prize. By Savannah Gignac, Assistant Photo Librarian. When Germany invaded Denmark during World War II, the Nazis were ready to confiscate the gold Nobel Prizes of German physicists Max von Laue (1914 recipient) and James Franck (1925 recipient).
