Hans Geiger (1882-1945) invented the Geiger counter. 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. In 1907, Nobel Prize laureate Ernest Rutherford became head of the physics institute in Manchester. Once given a dose large enough to track, officers could follow suspects, their documents and money with geiger counters. Reference : Wiki, StarsNetworths, Newspapers. The second, referring to his work with Marsden, dealt with "The Scattering of Alpha-Particles by Matter." In 1911 Geiger and John Mitchell Nuttall discovered the GeigerNuttall law (or rule) and performed experiments that led to Rutherford's atomic model.[7]. [2] He received a fellowship to the University of Manchester and worked as an assistant to Arthur Schuster.

[8] Work was interrupted when Geiger served in the German military during World War I as an artillery officer from 1914 to 1918. The years spent crouching in trenches on the front lines left Geiger with painful rheumatism. The chance of an -particle being reflected back was just 1 in 10^1,000 (1 followed by a thousand zeroes). A radioactive source emitting alpha particles (i.e., positively charged particles, identical to the helium atom nucleus and 7,000 times more massive than electrons) was enclosed within a . [1] Best known for designing the lanky, drooling Xenomorph for 1979s Alien, much of his life was devoted to studies in biomechanical visions. Manage Settings By 1904, Thomson (opens in new tab) had suggested a "plum pudding model" of the atom in which an atom comprises a number of negatively charged electrons in a sphere of uniform positive charge, distributed like blueberries in a muffin. Yet, when Geiger and Marsden conducted their eponymous experiment, they found that in about 2% of cases, the -particle underwent large deflections. Also in 1912 Geiger returned to Germany to take up a post as director of the new Laboratory for Radioactivity at the Physikalisch-Technische Reichsanstalt in Berlin, where he invented an instrument for measuring not only alpha particles but beta rays and other types of radiation as well.

In the atomic era, the Geiger-Mller Counter, as it is officially known, is an indispensable piece of equipment for all radiation physicists. As these men were politically conservative, their decision to oppose the National Socialists was taken seriously, and seventy-five of Germany's most notable physicists put their names to the Heisenberg-Wien-Geiger Memorandum. These experiments revealed that the angle of scattering of the -particle was proportional to the square of the charge of the atomic nucleus, or Z, according to the book (opens in new tab) "Quantum Physics of Matter," published in 2000 and edited by Alan Durrant. In 1925 Geiger used his counter to confirm In 1938 Geiger was awarded the Hughes Medal from the Royal Academy of Science and the Dudell Medal from the London Physics Society. After completing his compulsory military service, he studied physics at the University of Munich, and at the University of Erlangen where his tutor was Professor Eilhard Wiedemann. Before he was famous, He earned his doctorate in mathematics and physics from the University of Erlangen in 1906. Geiger designed the Childhood & Early Life. The Geiger-Marsden experiment, also called the gold foil experiment or the -particle scattering experiments, refers to a series of early-20th-century experiments that gave physicists their first view of the structure of the atomic nucleus and the physics underlying the everyday world.
