Round 9: Tossup 6

The differential cross section of a process named for this scientist equals the cosecant of theta over two all to the fourth power. That scattering process named for this scientist occurs when charged particles are deflected due to (15[1])a Coulombic (-5[1])interaction. Hans Geiger and Ernest Marsden performed an experiment formulated by this scientist which utilized a (*) screen coated with zinc sulfide. The term “gamma ray” was coined by this scientist, who disproved the Plum Pudding model in an experiment which measured the scattering patterns of alpha particles. (10[1])For (10[1])10 points, name this scientist who conducted the gold foil (10[1])experiment. ■END■ (10[1])

ANSWER: Ernest Rutherford [accept Rutherford scattering or Rutherford’s gold foil experiment]
