HOME SITE HELP ABOUT SEARCH ... EDUCATIONAL 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

FRANCIS WILLIAM ASTON F rancis William Aston lived in the years 1877-1945. He studied at Cambridge and was a Rutherford's student. After studies he became Thomson's assistant. They researched together the canal rays - they discovered that neon is a mixture of two components of a different mass - isotopes H e was intrigued by isotopes and driven by the desire to isolate them. To that aim he constructed a special device - a mass spectrograph . Aston researched 213 out of the total of 276 isotopes. He became a Cambridge University professor and a Royal Society member. In 1922 he was awarded the Nobel prize. I n subsequent years the scientist constructed new models of the mass spectrograph and researched isotopes in more detail.

Francis William Aston From Wikipedia, the free encyclopedia. (Redirected from Francis Aston 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
