Photographic method Discovery of the pion Notable awards Nobel Prize in Physics Cecil Frank Powell (5 December 1903 – 9 August 1969) was a British physicist, and Nobel Prize in Physics laureate for his development of the photographic method of studying nuclear processes and for the resulting discovery of the pion (pi-meson), a heavy subatomic particle. Life and career Powell was born in Tonbridge , Kent, England, the son of a local gunsmith, and educated at a local elementary school before gaining a scholarship to the Judd School , Tonbridge, which now has one of its four houses named after Powell, and awards the Powell Physics and Mathematics Prize to an upper sixth form student every year in his honour.

Powell, Cecil Frank English physicist who investigated the charged subatomic particles in cosmic radiation by using photographic emulsions carried in weather balloons. This led to his discovery of the pion ( meson) 1947, a particle whose existence had been predicted by Japanese physicist Hideki Yukawa 1935. Powell was awarded a Nobel prize 1950. Powell was born in Tonbridge, Kent, and studied at Cambridge, where he carried out research at the Cavendish Laboratory under Ernest Rutherford and C T R Wilson , taking photographs of particle tracks in a cloud chamber. From 1928 Powell worked at the Wills Physics Laboratory at Bristol University, becoming professor 1948. In 1938, instead of photographing the cloud-chamber tracks, Powell made the ionizing particles trace paths in the emulsions of a stack of photographic plates. The technique received a boost with the development of more sensitive emulsions during World War II and Powell used it in his discovery of the pion. He collaborated with Italian physicist Giuseppe Occhialini (1907- ), and together they published Nuclear Physics in Photographs 1947, which became a standard text on the subject.

If you are not immediately redirected, please click here Powell, Cecil Frank, 1903-1969. Papers and correspondence of Cecil Frank Powell, 1919-2002. Original material: Contains biographical material (including three chapters of an uncompleted autobiography), speeches and publications. There are 105 manuscript notebooks which fall into three separate groups: Cambridge notes by Powell on lectures by Rutherford, C. T. R. Wilson and others; Bristol notebooks, 1939-1949, of cosmic ray observations by Powell and his team; and notebooks of miscellaneous material such as drafts by Powell for his own lectures, speeches or publications, notes taken at conferences, etc. There are also journals, notebooks and reports relating to the Royal Society expedition to Montserrat in 1936 to investigate earth tremors on which Powell served as seismologist. Except for a few letters dealing with publications, there is no personal or professional correspondence. Documents (including correspondence) dealing with Powell's work for international organisations were destroyed after his death. First supplementary accession: TIncludes biographical material such as congratulatory letters on the Nobel Prize, Powell's sixtieth birthday and the Lomonosov Gold Medal, and family letters. Powell's research is represented chiefly by contemporary letters recording the high altitude balloon flights in Sardinia in 1952 and 1953. There are also photographs relating to Powell's scientific work and some drafts for lectures, addresses and broadcasts. Powell's public life in national and international affairs remains scantily documented, only a few records of Pugwash conferences and a little correspondence, disproportionately skewed towards the second half of the alphabet, surviving what was believed to be the wholesale destruction of his correspondence and papers after his death.
