Francis William Aston From Wikipedia, the free encyclopedia. Francis William Aston (born Birmingham September 1 ; died Cambridge November 20 ) was a British physicist who won the Nobel Prize in Chemistry for the invention of the mass spectrometer In he won a scholarship to the University of Birmingham and it was in his studies of electronic discharge tubes there that he discovered the phenomenon now known as the Aston Dark Space . In he moved to the Cavendish Laboratory in Cambridge on the invitation of J.J. Thomson and worked on the identification of isotopes of the element neon . Returning to these studies after the First World War in , he used a method of electromagnetic focusing to invent the mass spectrograph , which rapidly allowed him to identify no fewer than 212 of the 287 naturally occurring isotopes. His work on isotopes also led to his formulation of the Whole Number Rule which states that "the mass of the oxygen isotope being defined, all the other isotopes have masses that are very nearly whole numbers," a rule that was used extensively in the development of nuclear energy Retrieved from " http://en.wikipedia.org/wiki/Francis_William_Aston

Aston, Francis William Francis William Aston Corbis-Bettmann (b. Sept. 1, 1877, Harborne, Birmingham, Eng.d. Nov. 20, 1945, Cambridge, Cambridgeshire), British physicist who won the Nobel Prize for Chemistry in 1922 for his development of the mass spectrograph, a device that separates atoms or molecular fragments of different mass and measures those masses with remarkable accuracy. Aston used the mass spectrograph to discover a large number of nuclide s, or nuclear species that differ in mass. The mass spectrograph is widely used in geology, chemistry, biology, and nuclear physics. Aston was trained as a chemist, but, upon the rebirth of physics following the discovery of X rays in 1895 and of radioactivity in 1896, he began in 1903 to study the creation of X rays by the flow of current through a gas-filled tube. In 1910 he became an assistant to Sir J.J. Thomson at Cambridge, who was investigating positively charged rays emanating from gaseous discharges. During Aston's assistantship Thomson obtained, from experiments with neon, the first evidence for isotopes (atoms of the same element that differ in mass) among the stable (nonradioactive) elements. After World War I, Aston constructed a new type of positive-ray apparatus, which he named a mass spectrograph. It showed that not only neon but also many other elements are mixtures of isotopes. Aston's achievement is illustrated by the fact that he discovered 212 of the 287 naturally occurring nuclides.

Aston, Francis William Francis William Aston was born in September 1877 at Harborne, Birmingham, England, the third of a family of seven children. He was educated at Harborne Vicarage School and Malvern College where his interest in science was aroused. In 1894 he entered Mason College, Birmingham (later to become the University of Birmingham) where he studied chemistry under Frankland and Tilden, and Physics under Poynting. His winning of the Forster Scholarship in 1898 enabled him to work on the optical properties of tartaric acid derivatives; the results of this work were published in 1901. Leaving academic life for a time, he worked for three years as a chemist in the laboratory of a brewery. At about this time, however, his interest in physics, rather than chemistry, began to predominate; his aptitude for mechanical contrivance showed itself in his design and construction of new types of pumps for evacuating vessels. From this stemmed his interest in gas discharge phenomena in evacuated tubes. In 1903 he obtained a scholarship to Birmingham University (as it had now become) to work on the properties of the Crookes Dark Space in discharge tubes. Within a short time he had discovered the phenomenon which is known as the Aston Dark Space. At the end of 1909 he accepted the invitation of Sir J.J.Thomson to work as his assistant at the Cavendish Laboratory, Cambridge, on studies of positive rays. It was during this period that he obtained definite evidence for the existence of two isotopes of the inert gas neon.
