Aston francis william Aston, Francis William (Science: person , radiobiology) physicist at Cambridge university who invented the mass spectrometer in 1919, a device which could measure the mass of individual atoms . This device led to his discovery that the helium nucleus was less massive than the two hydrogen nuclei which could have formed it (implying that the missing mass could somehow be converted into energy through the process of nuclear fusion).

Aston, Francis William Aston, Francis William (1877-1945), britischer Chemiker, Physiker und Nobelpreistr¤ger, der den Massenspektrographen entwickelte und damit zahlreiche Isotope von nicht radioaktiven Elementen entdeckte. Aston wurde am 1. September 1877 in Harborne (Birmingham) geboren. Bereits in der Schule und am Malvern College wuchs Astons Interesse f¼r naturwissenschaftliche Themen. 1894 begann er am Mason College das Physik- und Chemiestudium – das College wurde 1900 in die Universit¤t Birmingham umgewandelt. 1898 erhielt er ein Stipendium und fertigte eine Arbeit ¼ber die Stereochemie bestimmter Derivate der Weins¤ure an. 1900 verlieŸ er die Universit¤t und fand eine Anstellung als Chemiker im Laboratorium einer Brauerei. Hier stellte der Forscher seine F¤higkeiten im Bereich Physik und Technik unter Beweis. Er entwickelte neuartige Pumpensysteme zum Evakuieren von Kesseln.

Conclusi gli studi presso il Malvern College dell’Universit  di Birmingham, e il Trinity College di Cambridge, si dedic² alle ricerche sulla massa atomica degli elementi e, nel 1919, costru¬ il primo spettrometro di massa Le accuratissime misure delle masse isotopiche che Aston ottenne con il nuovo strumento gli permisero di dedurre che tutti gli elementi, allo stato naturale, sono in realt  una miscela di vari isotopi con pesi atomici leggermente differenti. Giunse anche a rilevare il difetto di massa, ossia la differenza tra la somma delle masse delle singole particelle che costituiscono il nucleo, e la massa del nucleo allo stato legato, dal quale ¨ possibile determinare l’energia di legame del
