Yet, when Geiger and Marsden conducted their eponymous experiment, they found that in about 2% of cases, the -particle underwent large deflections. That same year, Geiger moved to Manchester University in England to join its esteemed physics department. His solution was an early version of the "Geiger counter," an electrical machine designed to count released alpha particles. Later that year in 1906 Hans Geiger was awarded the John Harlis Fellowship Award. "Memories of Rutherford in Manchester," in Nature, Volume 141, 1938, p. 244. Omissions? Thirty years later Geiger recollected, "At first we could not understand this at all," Wilson noted. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list. Of course, an -particle passing through an extremely thin gold foil would still encounter about 1,000 atoms, and thus its deflections would be essentially random.

Hans Geiger was awarded with the Hughes Medal in 1929 "for his invention and development of methods of counting alpha and beta particles". The research team calculated that if Thomson's model was correct, the maximum deflection should occur when the -particle grazed an atom it encountered and thus experienced the maximum transverse electrostatic force. * Hans Geiger is a German physicist. He continued experimenting and improving the counter. These results were published in two joint papers in 1908 entitled "An Electrical Method of Counting the Number of Alpha Particles" and "The Charge and Nature of the Alpha Particle.". During his school years, Geiger already displayed an interest in mathematics and natural sciences. [CDATA[ It was, rather, the constellation of evidence available gradually from the spring of 1913 and this, in turn, coupled with a growing conviction, tended to increase the significance or extrinsic value assigned to the Geiger-Marsden results beyond that which they intrinsically possessed in July 1912.".
