The nucleus was postulated as small and dense to account for the scattering of alpha particles from thin gold foil, as observed in a series of experiments performed by undergraduate Ernest Marsden under the direction of Rutherford and German physicist Hans Geiger in 1909. As a result of his efforts, he was able to discover bursts of radiation called cosmic-ray showers, and he concentrated on their study for the rest of his career. 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 . The inventor of the Geiger counter Hans Geiger became an ardent Nazi supporter and facilitated sending some fellow scientists into concentration camps. In addition, it can aslo locate a speeding alpha particle within about one centimeter in space and within a hundreth-millionth second of time. Tweet This, Mary E.
