Rudolf Mössbauer - Facts

Rudolf Ludwig Mössbauer

Rudolf Ludwig Mössbauer

Born: 31 January 1929, Munich, Germany

Died: 14 September 2011

Affiliation at the time of the award: Technical University, Munich, Federal Republic of Germany, California Institute of Technology (Caltech), Pasadena, CA, USA

Prize motivation: "for his researches concerning the resonance absorption of gamma radiation and his discovery in this connection of the effect which bears his name"

Field: nuclear physics

Prize share: 1/2


According to the principles of quantum physics, the atomic nucleus and surrounding electrons can have only fixed energy levels. When there are transitions among energy levels in the atomic nucleus, high-energy protons known as gamma rays are emitted and absorbed. In a gas a recoil effect occurs when an atom emits a photon. In 1958 Rudolf Mössbauer discovered that the recoil can be eliminated if the atoms are embedded in a crystal structure. This opened up opportunities to study energy levels in atomic nuclei and how these are affected by their surroundings and various phenomena.
