Ben Roy Mottelson Net Worth

Ben Roy Mottelson was bornon July 09, 1926 in Chicago, Illinois, U.S., American, is Physicist. Ben Roy Mottelson is an American-Danish nuclear physicist. Brought up in the suburbs of Chicago, he graduated from high school, when the Second World War was at its peak and was immediately enlisted in the military. However, he spent the war years at the University of Purdue, getting trained to become a Navy Officer. After the war, he earned his bachelor’s degree from Purdue University and then his PhD from Harvard University. Subsequently, he traveled to Copenhagen, where he joined the Institute for Theoretical Physics (later the Niels Bohr Institute) on fellowship. There, he began collaborating with Aage Bohr and experimentally confirmed that movement of subatomic particles can alter the shape of the nucleus. This work, which earned them the Nobel Prize in Physics two decades later, not only challenged the established theories, but also stimulated further studies in this field. Soon after this, he obtained employment, first at the Theoretical Study Group of European Organization for Nuclear Researc, and then at Nordisk Institut for Teoretisk Atomfysik, both in Copenhagen. Later he became a naturalized citizen of Denmark and now lives in Copenhagen.

Biography/Timeline

1947

Mottelson was born in Chicago, Illinois, the son of Georgia (Blum) and Goodman Mottelson, an Engineer. He graduated from Lyons Township High School in LaGrange, Illinois. He received a Bachelor's degree from Purdue University in 1947, and a Ph.D. in nuclear physics from Harvard University in 1950.

1948

Mottelson has dual citizenship. He has both Danish and American citizenship. He lives in Copenhagen, Denmark. Mottelson was married to Nancy Jane Reno from 1948 until her death in 1975. They had two sons and one daughter. Mottelson then married Britta Marger Siegumfeldt in 1983.

1950

In 1950–51, James Rainwater and Aage Bohr had developed Models of the atomic nucleus which began to take into account the behaviour of the individual nucleons. These Models, which moved beyond the simpler liquid drop treatment of the nucleus as having effectively no internal structure, were the first Models which could explain a number of nuclear properties, including the non-spherical distribution of charge in certain nuclei. Mottelson worked with Aage Bohr to compare the theoretical Models with experimental data. In three papers which were published in 1952–53, Bohr and Mottelson demonstrated close agreement between theory and experiment, for Example showing that the Energy levels of certain nuclei could be described by a rotation spectrum. This work stimulated new theoretical and experimental studies.

1953

He moved to Institute for Theoretical Physics (later the Niels Bohr Institute) in Copenhagen on the Sheldon Traveling Fellowship from Harvard, and remained in Denmark. In 1953 he was appointed staff member in CERN's Theoretical Study Group, which was based in Copenhagen, a position he held until he became professor at the newly formed Nordic Institute for Theoretical Physics (Nordita) in 1957. He was a visiting professor at the University of California, Berkeley in Spring 1959. In 1971 he became a naturalized Danish citizen.

1969

He is a foreign fellow of Bangladesh Academy of Sciences and the Norwegian Academy of Science and Letters. In 1969, he received the Atoms for Peace Award. He acted as Director of ECT* (Trento, Italy) from 1993 to 1997.

1975

Rainwater, Bohr and Mottelson were jointly awarded the 1975 Nobel Prize in Physics "for the discovery of the connection between collective motion and particle motion in atomic nuclei and the development of the theory of the structure of the atomic nucleus based on this connection".
