Erich Gerdau
Erich Gerdau (born May 20, 1935 ) is a German experimental physicist. He is a professor at the University of Hamburg .
Gerdau received his doctorate in 1966 at the University of Hamburg (investigations on the Hf 176 and Hf 180 using the Mössbauer effect ).
Gerdau combined Mössbauer spectroscopy with synchrotron radiation sources and demonstrated coherent elastic nuclear resonance scattering (NRS) of synchrotron radiation in 1985 (carried out at DESY ). This opened up a new perspective in Mössbauer spectroscopy through the use of synchrotron radiation sources instead of radioactive materials as sources. Further technical developments in the 1990s (such as 3rd generation synchrotron radiation sources, high-resolution X-ray optics and avalanche photodiodes ) made Mössbauer spectroscopy with synchrotron beams a standard method in materials research, with isotopes in very low concentrations thanks to the much higher brilliance of the radiation , thin films, nanostructures and matter could be examined under extreme conditions.
In 1988 he received the Stern-Gerlach Prize .
