Max Planck. Signature. Lise Meitner (/ ˈliːzə ˈmaɪtnər / LEE-zə MYTE-nər, German: [ˈliːzə ˈmaɪtnɐ] ⓘ; born Elise Meitner, 7 November 1878 – 27 October 1968) was an Austrian physicist who was instrumental in the discovery of protactinium and nuclear fission. Completing her doctoral research in 1905, Meitner became the second ...
The nuclear reaction theorised by Meitner and Frisch and observed by Hahn and Strassmann. Nuclear fission was discovered in December 1938 by chemists Otto Hahn and Fritz Strassmann and physicists Lise Meitner and Otto Robert Frisch. Fission is a nuclear reaction or radioactive decay process in which the nucleus of an atom splits into two or ...
Otto Hahn (pronounced [ˈɔtoː ˈhaːn] ⓘ; 8 March 1879 – 28 July 1968) was a German chemist who was a pioneer in the fields of radioactivity and radiochemistry. He is referred to as the father of nuclear chemistry and father of nuclear fission. Hahn and Lise Meitner discovered radioactive isotopes of radium, thorium, protactinium and uranium.
Lise Meitner was left off the publication that eventually led to a Nobel Prize for her colleague. Nuclear fission – the physical process by which very large atoms like uranium split into pairs ...
Otto Robert Frisch OBE FRS [1] (1 October 1904 – 22 September 1979) was an Austrian-born British physicist who worked on nuclear physics. With Otto Stern and Immanuel Estermann he first measured the magnetic moment of the proton. With Lise Meitner he advanced the first theoretical explanation of nuclear fission (coining the term) and first ...
The Einstein–Szilard letter was a letter written by Leo Szilard and signed by Albert Einstein on August 2, 1939, that was sent to President of the United States Franklin D. Roosevelt. Written by Szilard in consultation with fellow Hungarian physicists Edward Teller and Eugene Wigner, the letter warned that Germany might develop atomic bombs ...
Nuclear fission is a reaction in which the nucleus of an atom splits into two or more smaller nuclei. The fission process often produces gamma photons, and releases a very large amount of energy even by the energetic standards of radioactive decay. Nuclear fission was discovered by chemists Otto Hahn and Fritz Strassmann and physicists Lise ...
It has been well documented in many biographies, and also in Rispens' book, that Debye and Dutch colleagues helped his Jewish colleague Lise Meitner in 1938–1939 (at great risk to himself and his family [17] [18]) cross the Dutch-German border to escape Nazi persecution and eventually obtain a position in Sweden.
