Bethe , Hans Albrecht HE IS STILL ALIVE? Bethe , Hans Albrecht (1906- ), German-born American physicist and Nobel laureate, noted for his contributions to theories of stellar energy production. Bethe was born in Strasbourg, Alsace-Lorraine (then a part of Germany), and educated at the University of Frankfurt and the University of Munich, from which he received a Ph.D. degree in 1928. Bethe taught physics at various universities in Germany from 1928 to 1933 and in England from 1933 until 1935, when he began his long association with Cornell University. Beginning in 1943 he worked at Los Alamos, New Mexico, on the atomic-bomb project. After initial misgivings he took part in the later development of the hydrogen bomb. At the same time he continued his work for the peaceful use and international control of nuclear energy. A prime advocate of the partial test-ban agreement signed by the United States, the Soviet Union, and the United Kingdom in 1963, he became an opponent of the Strategic Defense Initiative, proposed by the United States in the 1980s. Bethe was awarded the 1967 Nobel Prize in physics for his studies of the production of energy by the sun and other stars, which he postulated occurs through thermonuclear fusion, a long series of nuclear reactions by which hydrogen is converted into helium. He was naturalized a U.S. citizen in 1941.

Britannica CD Index Articles Dictionary Help Bethe, Hans Albrecht (b. July 2, 1906, Strassburg, Ger. [now Strasbourg, Fr.]), German -born American theoretical physicist who helped to shape classical physics into quantum physics and increased the understanding of the atomic processes responsible for the properties of matter and of the forces governing the structures of atomic nuclei. He received the Nobel Prize for Physics in 1967 for his work on the production of energy in stars. Moreover, he was a leader in emphasizing the social responsibility of science. Bethe studied physics at the University of Frankfurt and did research in theoretical physics at the University of Munich, where he obtained the doctorate in 1928. His doctoral thesis, on the theory of electron diffraction, remains of fundamental value in understanding observational data. His work on term splitting in crystals in 1929 showed how the symmetrical electric field by which an atom in a crystal is surrounded affects its energy In 1939 Bethe calculated the Sun's energy production, which results from the fusion of four hydrogen atoms (each of mass 1.008) into one helium atom (mass 4.0039). No direct fusion is possible, but Bethe showed that the probabilities of the four steps of the "carbon cycle" can account for the energy output. A carbon isotope of mass 12 reacts successively with three hydrogen nuclei (protons) to form the nitrogen isotope of mass 15; energy is produced through the fusion of a fourth hydrogen nucleus to release a helium nucleus (alpha particle) and the original carbon isotope.

After the rise of the Nazis in Germany, Bethe emigrated to England in 1933 where he held teaching positions at the University of Manchester and the University of Bristol. In 1935, Bethe received the position of Assistant Professor at Cornell University. During 1935-1939, Bethe's main achievement in astrophysics was the exclusion of many possible interactions than can happen inside the stars, leaving just two possibilities: the carbon-nitrogen cycle for massive stars and proton-proton reaction that powers fainter stars like the Sun.

PHYSICISTS ASTROPHYSICISTS A B ... CONTACT entire Web this site German-born American theoretical physicist who, in 1938, worked out the details of the proton-proton chain , the main energy-producing reaction in stars less massive than the Sun, and, in the same year, with Carl von Weizsäcker , developed the theory of the carbon-nitrogen-oxygen cycle , which powers the Sun and more massive stars. For this work, he was awarded the 1967 Nobel Prize in Physics. Bethe studied at the Universities of Frankfurt and Munich, where he earned his Ph.D. under Arnold Sommerfeld (1928). He made important contributions to the theories of electrons in crystals, the negative hydrogen ion, and the passage of charged particles through matter, before leaving Germany in 1933 for England. There he began working in nuclear physics, and he and Rudolph Peierls developed the theoretical model of the deuteron shortly after its discovery. Bethe spent most of his career as professor of theoretical physics at Cornell University (193575). His three review articles in the late 1930s (two of them with coauthors) became known as "Bethe's Bible" and formed the first textbook of nuclear physics. At the beginning of World War II, Bethe formed a theory of the penetration of armor by projectiles, and, with Edward Teller, produced a major paper on
