Nobel Foundation Nobel Media Nobel Museum Nobel Peace Center ... Prize in Economics Francis W. Aston The Nobel Prize in Chemistry 1922 Biography 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

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 Francis William Aston 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 nuclides, 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.

He was awarded the Nobel Prize for Chemistry in 1922 for his contribution to analytic chemistry and the study of atomic theory . Aston was born and educated in Birmingham. From 1910 he worked in the Cavendish Laboratory, Cambridge, where J J Thomson was investigating positive rays from gaseous discharge tubes. Thomson and Aston examined the effects of electric and magnetic fields on positive rays, showing that the rays were deflected depending on their mass. The deflected rays were made to reveal their positions by aiming them at a photographic plate. The image produced on the photographic plate became known as a mass spectrum, and the instrument itself as a mass spectrometer. This became an essential tool in the study of nuclear physics and later found application in the determination of the structures of organic compounds. Aston first examined neon gas and found that it consists of two isotopes. Over the next few years he examined the isotopic composition of more than 50 elements, and published

London, 1922. Aston's invention of the mass spectrograph, an instrument giving a concentrated and extremely detailed breakdown of the constituents of analyzed material, enabled him to discover that elements are composed of atoms of varying mass, and that the atomic weight of an element is an average of the atoms comprising it. Aston used the word "isotopes" to describe atoms of differing weights within the same element, a term first coined by Frederick Soddy to describe separate elements that are nevertheless homogeneous in chemical behavior.

Library Biographies Francis William Aston Francis William Aston Born in Birmingham, England in September 1877, Francis William Aston was fascinated by science at an early age. In 1894, Aston attended Birmingham University to study chemistry and physics. Aston won the Forster Scholarship in 1898, allowing him to conduct research that was published in 1901. He began working as an assistant at Cavendish Laboratory in Cambridge in 1909 and conducted research on positive rays. Aston remained at Cavendish until1914 when World War I required his skills at the Royal Aircraft Establishment. After World War I ended, Aston returned to his studies at Cavendish, now focusing on isotopes. In 1919, Aston made his most significant contribution to atomic science with the Printer Friendly More on the Web Alsos Digital Library for Nuclear Issues Nobel eMuseum invention of the mass spectrograph. The device was capable of separating isotopes by measuring the minute differences in their masses. Using the mass spectrograph, Aston successfully identified 212 existing isotopes. The invention also prompted him to devise his famous Whole Number Rule which states, "the mass of the oxygen isotope being defined, all the other isotopes have masses that are very nearly whole numbers." The rule became crucial to future developments in nuclear energy technology.
