The event, known as the Münchner Religionsgespräche ("Munich Synod"), signaled the decline of the influence of the deutsche Physik (German physics) movement.

Supporters of deutsche Physik launched vicious attacks against leading theoretical physicists, including Arnold Sommerfeld and Werner Heisenberg.

Alfons Bühl, a supporter of deutsche Physik, invited Harald Volkmann, Bruno Thüring, Wilhelm Müller, Rudolf Tomaschek, and Ludwig Wesch.

[16] While the technical outcome of the event may have been thin, it was a political victory against deutsche Physik and signaled the decline of the influence of the movement within the German Reich.

[17][18] In 1933, shortly after Adolf Hitler became Chancellor, the Law for the Restoration of the Professional Civil Service was passed, which resulted in resignations and emigrations of many physicists, one of them was James Franck, who was director of the II.

In 1935, an ordinance related to the Civil Services act, the Law on the Retirement and Transfer of Professors as a Result of the Reorganization of the German System of Higher Education, was used to forcibly transfer Georg Joos to Göttingen to fill Frank's position as ordinarius professor and director of the Second Physics Institute.

Additionally, he built a 6-MeV betatron, studied atomic beams, resonance, and the biological effects of radiation, and developed methods of optical interferometry.

[19][20] As a principal in the Uranverein, Kopferman, with a couple of physicists under his direction, investigated and developed isotope separation techniques; their work included the construction of a mass spectrograph.

Other members of the Nuclear Physics Working Group in both 1956 and 1957 were: Werner Heisenberg (chairman), Hans Kopfermann (vice-chairman), Fritz Bopp, Walther Bothe, Wolfgang Gentner, Otto Haxel, Willibald Jentschke, Heinz Maier-Leibnitz, Josef Mattauch, Wolfgang Riezler [de], Wilhelm Walcher, and Carl Friedrich von Weizsäcker.
