Börngen and L. D. Schmadel at Tautenburg. German Rudolf Ludwig Mössbauer (b. 1929) received with R. Hofstadter the Nobel Prize in physics in 1961 for his discovery of the recoil-free \gamma -ray resonance absorption (Mössbauer effect), which has wide application in nuclear physics, solid-state physics and chemistry.
