(February 23, 2023). Geiger's simple but ingenious measuring device enabled him and Rutherford to discern that alpha particles are, in fact, doubly charged nuclear particles, identical to the nucleus of helium atoms traveling at high velocity. Ridley Scott had no idea how he was going to proceed with the art direction for Alien, a script he agreed to direct about a space crew that inadvertently picks up a dangerous, acid-blooded passenger. In 1911 Geiger and John Mitchell Nuttall discovered the GeigerNuttall law (or rule) and performed experiments that led to Rutherford's atomic model.[7].

In 1920, James Chadwick used a similar experimental setup to determine the Z value for a number of metals. Regarding his time in England, he wrote to Max von Laue: If I have been able to do something for our physics, than I owe this more than anything to the good fortune of having come into contact with Rutherford at an early stage of my life.. New Haven, CT: Yale University Press, 1979. ", Geiger's results were accurate enough to persuade Rutherford to go public with his discovery in 1910. [12], Beginning in 1939, after the discovery of atomic fission, Geiger was a member of the Uranium Club, the German investigation of nuclear weapons during World War II. Rutherford was to have a profound influence on young Geiger, sparking his interest in nuclear physics.
