Today (January 31, 1929) is the birthday of Rudolf Mössbauer, winner of the Nobel Prize in Physics for his discovery of the Mössbauer spectrum.

Today (January 31, 1929) is the birthday of Rudolf Mössbauer, winner of the Nobel Prize in Physics for his discovery of the Mössbauer spectrum.

Rudolf Ludwig Mössbauer was born on January 31, 1929, in Munich. He also studied physics at the Munich University of Technology. He graduated in 1955 with a diploma in Haynes Meyer-Leibniz Applied Physics Laboratory. He then went to the Max Planck Institute for Medical Research in Heidelberg. Manpower was under the patronage of Meyer-Leibniz, his official research adviser, when he passed the PhD examination in Munich in 1958, as the institute was not part of a university and was not entitled to a doctorate. In his PhD work, he discovered the irreversible nuclear luminosity of gamma rays at 191 iridium.

His popularity grew exponentially in the 1960s when Robert Pound and Glenn Repka used this effect to demonstrate the redshift of gamma radiation at the Earth's gravitational pull. This pound-Repka test was one of the first experimental precision tests of Albert Einstein's general theory of relativity. However, the long-term significance of the Mössbauer effect is its use in the Mössbauer spectrum. Together with Robert Hofstadter, Mössbauer was awarded the 1961 Nobel Prize in Physics. On the advice of Richard Feynman, Mössbauer was invited to Caltech in the United States in 1960. There he progressed rapidly from a Research Fellow to a Senior Research Fellow. He was appointed full professor of physics in early 1962. In 1964, his alma mater persuaded him to return as a full-time professor at the University Of Technology (TUM) in Munich.

Conventional Mössbauer Spectroscopy

He retained this position until he became Professor Emeritus in 1997. As a condition for his return, the Faculty of Physics introduced a "field" system. This system was strongly influenced by the US experience in Mössbauer. This is in stark contrast to the traditional, hierarchical "Department" system of German universities. It also gave TUM is a better place in German physics. In 1972, when the newly built high-flux research reactor came into operation, Rudolf Mössbauer went to Grenoble to succeed Heinz Meyer-Leibniz as director of the Institute Law-Lange. After a 5-year hiatus, Mössbauer returned to Munich. There he reformed his institutional reforms by a very high law. Until the end of his career, he often expressed bitterness about this "destruction of the department." Meanwhile, his research interests shifted to neutrino physics.

Mössbauer was considered an excellent teacher. He has lectured extensively on many subjects, including neutrino physics, neutrino oscillation, the integration of electromagnetic and weak interactions, and the reactivity of photons and neutrons. In 1984, he gave undergraduate lectures to 350 people taking physics courses. He told his students: “Explain it! The most important thing is that you are acanain it! You will have exams, there you have to explain them. Eventually, you pass them, you get your diploma an,d you think that's it! – No, the whole life is an exam, you'll have to write applications, you'll have to discuss with peers... So learn to explain it! You can train this by explaining to another student, a colleague. If they are not available, explain it to your mother – or to your cat!”

Most famous for his discovery of irreversible atomic vibration fluorescence in 1957. For this, he was awarded the 1961 Nobel Prize in Physics. This effect is called the Mössbauer effect. It is the basis for the Mössbauer spectrum. Rudolf Mössbauer, the winner of the Nobel Prize in Physics for his discovery of the Mössbauer spectrum, passed away on September 14, 2011, in Germany at the age of 82.
