For his experimental work on the photoelec hie effect, Millikan was awarded the Nobel Prize in physics in 1923. Others whose contributions to the understanding of radiation led to Nobel Prizes in physics include Wilhelm Wien in 1911 for heat radiation laws, Planck in 1918 for the quantum concept, Johannes Stark in 1919 for spec rial properties, Einstein in 1921 in part for interpreting the photoelectric effect, Niels Bohr in 1922 for atomic radiation, James Franck and Gustav Hertz in 1925 for atom-electron interactions, and Wo If gang Pauli in 1945 for atomic properties.

Stark effect The splitting of atomic spectral lines because of the presence of an external electric field. This phenomenon was discovered by the German physicist Johannes Stark (1874-1957) in 1913.

Stark effect The splitting of lines in the spectra of atoms due to the presence of a strong electric field. It is named after the German physicist Johannes Stark (1874-1957), who discovered it in 1913. Like the normal Zeeman effect, the Stark effect can be understood in terms of the classical electron theory of Lorentz. The Stark effect for hydrogen atoms was also described by the Bohr theory of the atom. In terms of quantum mechanics, the Stark effect is described by regarding the electric field as a perturbation on the quantum states and energy levels of an atom in the absence of an electric field. This application of perturbation theory was its first use in quantum mechanics. 

The fundamental basis for Stark spectroscopy stems from Johannes Stark s discovery that electrical fields split lines in atomic spectra, which eventually led to his winning the 1919 Nobel Prize in physics. However, physicists did not begin to study Stark effects on the speetra of chemical systems until the 1970s. The field of study was subsequently expanded to coordination compounds. Among the earliest reports are those by Boxer and co-workers beginning in 1989. ...

In 1937 Werner Heisenberg was at the height of his powers. He was nominated professor and got married. However, just after returning from his honeymoon, the rector of the university called him, saying that there was a problem. In the SS weekly an article by Prof. Johannes Stark (a Nobel Prize winner and faithful Nazi) was about to appear claiming that Professor Heisenberg is not such a good patriot as he pretends, because he socialized in the past with Jewish physicists... 

Johannes Stark (1874-1957), Nobel Prize in Physics for his work on structural and spectral changes of atoms. His work is well described in Ann. Phys., 1914, 43, 965.

Physik movement, this entirely Jewish affair simply needs to be gotten rid of. His colleague, Johannes Stark, wanted a new spirit to be imposed upon the Society at the very least The Prussian Minister of Culture expressed a similar sentiment, which had more serious bureaucratic implications. It was hardly a coincidence, given the grounds for their criticism of the KWG, that they came to focus much of their attention on Haber s institute. As a result, in the following years, the Institute would become a textbook example of National Socialist science policy. ...
