, of the 1961 Nobel Prize in Physics for his research on the emission and absorption of gamma radiation by atomic nuclei. He discovered the Mössbauer effect, in which nuclei that are in a crystalline lattice, which prevents the nuclei from recoiling, can emit and absorb gamma radiation resonantly. It allows highly precise measurements of frequency and has been applied to problems ranging from investigations on the surface of Mars to studies of corrosion.

Mössbauer, Rudolf Ludwig


Born Jan. 31, 1929, in Munich. German physicist (Federal Republic of Germany).

In 1955, Mössbauer graduated from the Technische Hochschule in Munich. From 1955 to 1957 he was a research assistant at the Max Planck Institute in Heidelberg, and from 1957 to 1959 he was back at the Technische Hochschule, receiving his doctorate in 1958. In 1960 he was appointed senior research fellow at the California Institute of Technology, becoming a professor in 1961. In 1964 he was appointed a professor at the Technische Hochschule in Munich. His main works are in nuclear physics and solid-state physics. In 1958, Mössbauer discovered the phenomenon of resonance absorption of gamma quanta by the atomic nuclei of a solid without an accompanying change in the internal energy of the body (the Mössbauer effect). He was awarded a Nobel Prize in 1961.
