Isotopes are atoms which have the same chemical properties, but different atomic mass. For example, carbon can exist in its common form C or the less common form C . At the award ceremony it was acknowledged that while radioactive elements had readily shown the existence of isotopes, to prove that non-radioactive elements could be a mixture of different isotopes had been far from easy. JJ Thomson, himself a Nobel Laureate, had achieved inconclusive experimental results to this end, but his assistant, Aston, used a quartz microbalance and mass spectrograph to identify two isotopes of the element neon. He went on to employ his original mass spectrograph to find the different isotopes of about fifty elements.

85. Paul Kuroda Fellowship -- Biography In 1936 when Kuroda was 19, francis william aston visited Japan andgave a special lecture on Mass Spectra and Isotopes . Kuroda http://ua-cheme.engr.uark.edu/kuroda/bio.htm

Paul Kazuo Kuroda was born April 1, 1917 in Kurogi, Fukuoka Prefecture, Kyushu, Japan, the only son of Kanjiro and Shige Kuroda. His father was a school teacher and later an official at the Ministry of Education in Tokyo and a noted calligrapher. His paternal ancestors belonged to the samurai class in Fukuoka, the so-called Kuroda-Bushi (samurai of the Kuroda-clan), well-known among the Japanese. His maternal ancestors (according to his grandmother) can be traced to the 16th century warlord Shibata-Katsuie, the head retainer of Lord Oda - Nobunaga, who later became a Shogun. Kuroda grew up under the influence of the words of an American chemist, William Smith Clark (1826-1885), President of the Agricultural College of Massachusetts (now the University of Massachusetts) who in 1876 was invited by the Japanese government to come to Japan to establish an American-style university in Sapporo, Hokkaido. The Agricultural College of Sapporo (now the University of Hokkaido) was thus founded in 1877. When Clark left Japan to return to America, he turned in his saddle, waved at his students, and shouted in farewell, "BOYS! BE AMBITIOUS!" - a phrase still familiar to almost all Japanese.

89. ChemTeam: Aston - Isotopes And Atomic Weights By Dr FW aston Nature 105, p. 617. of opinion at the end of last century may begathered from the two following quotations from Sir william Ramsay s address http://dbhs.wvusd.k12.ca.us/webdocs/Chem-History/Aston-MassSpec.html

ISOTOPES AND ATOMIC WEIGHTS By Dr F. W. Aston Nature : 105, p. 617. In the atomic theory put forward by John Dalton in 1801 the second postulate was: "Atoms of the same element are similar to one another and equal in weight." For more than a century this was regarded by chemists and physicists alike as an article of scientific faith. The only item among the immense quantities of knowledge acquired during that productive period which offered the faintest suggestion against its validity was the inexplicable mixture of order and disorder among the elementary atomic weights. The general state of opinion at the end of last century may be gathered from the two following quotations from Sir William Ramsay's address to the British Association at Toronto in 1897: This idea was placed on an altogether different footing some ten years later by the work of Sir Ernest Rutherford and his colleagues on radio-active transformations. The results of these led inevitably to the conclusion that there must exist elements which have chemical properties identical for all practical purposes, but the atoms of which have different weights. This conclusion has been recently confirmed in a most convincing manner by the production in quantity of specimens of lead from radio-active and other sources, which, though perfectly pure and chemically indistinguishable, give atomic weights differing by amounts quite outside the possible experimental error. Elements differing in mass but chemically identical and therefore occupying the same position in the periodic table have been called "isotopes" by Prof. Soddy.
