Till Jahnke

Till Nikolaij Jahnke (born  February 17, 1977 in Frankfurt am Main ) is a German physicist .

Life

Jahnke attended the Musterschule , a grammar school in Frankfurt am Main , until 1996 . He then studied physics and computer science in Frankfurt . In 2002 he completed his diploma thesis on the development and construction of a gas target from metastable, spin-polarized He ^* , in which he dealt with high-pressure glow discharges . In 2005 he did his doctorate on the subject of Interatomic Coulombic Decay - Experimental investigation of a novel, interatomic de-excitation mechanism . After his habilitation in 2013, he became Professor of Experimental Atomic Physics at the Johann Wolfgang Goethe University in Frankfurt am Main in 2017 .

Scientific focus

Jahnke's scientific field of work is experimental atomic and molecular physics . Jahnke is a student of Horst Schmidt-Böcking and Reinhard Dörner . In his investigations he uses the Cold Target Recoil Ion Momentum Spectroscopy (COLTRIMS) measurement method, a technique that is often referred to as a reaction microscope or vector correlations . With the help of this measuring method, Jahnke investigates the dynamic relationships between electrons and nuclei within atoms and small molecules . His scientific focus is on studies with synchrotron radiation , femtosecond lasers and free-electron lasers . As part of his doctorate, he was able to provide unambiguous experimental evidence of an interatomic decay process called Interatomic Coulombic Decay , which he researched further in the following years. This electronic de-excitation process had been theoretically predicted 10 years earlier by Lorenz Cederbaum at the University of Heidelberg .
