	Francis William Aston - Wikipedia, the free encyclopedia
		Francis William Aston (born Birmingham, September 1, 1877; died Cambridge, November 20, 1945) was a British physicist who won the 1922 Nobel Prize in Chemistry for the invention of the mass spectrometer.
		In 1903 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 1909 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.

		Whilst working at the Cavendish Laboratory in Cambridge under J J Thomson, Francis William Aston (1877-1945) undertook a series of experiments that led to the discoveries by which he is now best remembered.
		Aston devised several methods for calibrating his instrument and, in the case of neon, obtained mass lines on his photographic plate at 20 and 22 with the intensities of the lines showing that the two particles occurred in the ratio of 10:1, consistent with an average mass of 20.20, the known atomic weight of neon.
		Aston was assigned to improving Thomson's apparatus in which a beam of positively-charged particles (positive rays) was deflected by a combination of electric and magnetic fields into sharp visible curves, each representing an individual particle's charge-to-mass ratio.

	Aston, Francis William
		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.
		Aston's achievement is illustrated by the fact that he discovered 212 of the 287 naturally occurring nuclides.
		Aston used the mass spectrograph to discover a large number of nuclides, or nuclear species that differ in mass.

	ASTON, FRANCIS WILLIAM (1877 - 1945)
		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 was awarded the Nobel Prize for chemistry in 1922 "for his discovery, by means of his mass spectrograph, of the isotopes of a large number of non-radioactive elements, as well as for his discovery of the whole-number rule."
		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.

		Aston reasoned that part of the mass of the protons and neutrons was converted into energy, which could be calculated using E = mc^2.
		Aston invents the Mass Spectrometer, a device capable of separating isotopes of an element and also accurately measuring isotope masses.
		Over the next two decades, Aston would identify 212 of the known stable isoptopes.

	Cambridge Physics - Splitting the Atom
		Aston's work was interrupted by the First World War, when he worked as a chemist at Farnborough in the Royal Aircraft Factory, investigating the canvas used to cover aeroplanes.
		Aston was first educated at Harborne Vicarage School, but began to study science at Malvern College, where he demonstrated his ability in chemistry, physics and mathematics.
		Aston had been recommended to Thomson by his former teacher Poynting, and was happy to accept the Cambridge post which would leave him more time for research.

		Although Aston Barrett believed that the settlement of this matter would mark the beginning of fair treatment between the Marley Estate and himself, the sad fact is that, since then, the Estate has kept songwriter and artist royalties paid to it by Island Records on behalf of the Barretts without distributing said monies to them.
		Aston becomes the musical director for the band and contributes bass, piano, organ and guitar on many of their songs while Carly plays the drums.
		In 1974 Aston Barrett and his brother, the band's drummer, were contracted along with Bob Marley by Island Records to produce Natty Dread, their first international and major label record.

	Aston isotopes: Teaching notes
		Notes: Francis Aston (1877-1945) worked in the laboratory of J. Thomson (best known for characterizing cathode rays, identifying the particle we now call the electron) at Cambridge University.
		Aston's work on cathode ray tubes focused on "positive rays", that is on the cations formed when electrons were stripped from the gases in the tube.
		Historical footnote: Aston's first preliminary results on neon date back to 1913, the same year as Frederick Soddy proposed the term "isotope." The concept of isotopes really came out of the study of radioactivity; however, the extension of the concept to stable elements came about almost immediately.

	Paul Kuroda Fellowship -- Biography
		Kuroda was greatly impressed and decided to study under Francis Aston, after graduating from the Imperial University of Tokyo.
		In 1936 when Kuroda was 19, Francis William Aston visited Japan and gave a special lecture on "Mass Spectra and Isotopes".
		He realized at once that the mass-spectrometer invented by Aston would play a key role in chemistry in the future, but he was disappointed to find that professors of chemistry in those days seemed to regard it as a tool for physicists, not for chemists.

		Aston returned to Cambridge after Word War I and constructed a new type of mass spectrograph and discovered the existence of isotopes in many elements (of 281 naturally-occurring isotopes, Aston discovered 212).
		He also calculated atomic weights from nuclidic masses and abundances, and brought about the use in physics of the mass of oxygen-16 as exactly 16, whence all other elements had nearly integer masses.
		In 1909 he became an assistant to J. Thomson at Cambridge and worked with him on many studies with the parabola mass spectroscope.
