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 a Coulombic interaction. (-5[1])Hans Geiger and Ernest Marsden (-5[1])performed an experiment formulated by this (15[1])scientist which utilized a (*) screen (10[1])coated with zinc (10[2])sulfide. The term “gamma ray” was coined by this (10[1])scientist, (10[1])who disproved the Plum Pudding model (10[1])in an experiment which measured the scattering patterns (10[1])of alpha particles. For 10 points, name this scientist who conducted the gold foil experiment. ■END■
