Francis William Aston (1877-1945) Francis William Aston foi físico experimental que nasceu em Harborne a 1 de Setembro de 1877, vindo a falecer em Cambridge em 20 de Novembro de 1945. Francis trabalhou com Frankland em 1898, Poynting em 1903 e J.J Thomson em 1910. A sua larga experiência em técnicas de vácuo permitiu-lhe pôr em evidência pela primeira vez a constituição isotópica de um elemento estável por meio de análise dos raios positivos. Em 1913 conseguiu uma separação parcial de isótopos por um método de difusão. Obteve o Prêmio Nobel da Química em 1922. voltar

ODKRYCIA W CHEMII I FIZYCE XIX I XX WIEKU Od 1898 roku do 1994 roku: Odkrycia cz¹stek elementarnych; Teorie chemiczne; Modele budowy atomu (Od modelu Thomsona do modelu Bohra- Sommerfelda); Kwarkowa struktura materii Ernest Rutherford ( 1871 - 1937) udowodni³, ¿e promieniowanie uranu jest promieniowaniem z³o¿onym z co najmniej dwóch ró¿nych rodzajów promieniowania. Promieniowanie ,które ³atwo ulega absorpcji Rutherford nazwa³ promieniowaniem alfa. Drugi rodzaj promieniowania o bardziej przenikliwym charakterze nazwa³ promieniowaniem beta. Charakterystykê podan¹ przez Ernesta Rutherforda w 1899 r. w pracy " Uranium Radiation and the Electrical Condution Produced by It" - Phil. Mag., 47, 114, 1899 uzupe³nili inni badacze, którzy wykazali, ¿e promienie alfa i beta s¹ z³o¿one z cz¹stek elektrycznie na³adowanych. Cz¹stki te ulegaj¹ odchyleniu w polu magnetycznym i elektrostatycznym odchyleniu, lecz w przeciwnych kierunkach. Stosunek e/m dla promieniowania beta wyznaczony przez Becquerela Henri ( 1852 - 1908) mia³ tak¹ sam¹ wartoœæ jak zmierzony przez Thomsona Josepha ( 1856 -1940) dla promieni katodowych ( elektronów).

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
