Packet 9: Tossup 6

The differential cross section of a process named for this scientist equals (-5[1])the cosecant of theta over two all to the fourth power. That scattering process (15[1])named for this scientist occurs when charged particles are deflected (-5[2])due to (15[1])a Coulombic (-5[2])interaction. (15[1]-5[1])Hans Geiger and Ernest (15[1])Marsden (15[1]-5[1])performed an experiment (15[1])formulated by (15[1])this (15[1])scientist (15[3])which (15[1])utilized (15[1])a (*) screen (10[2])coated (10[2])with zinc (10[2])sulfide. (10[1])The term “gamma (10[1])ray” (10[1])was coined by this (10[2])scientist, (10[2])who disproved (10[1])the Plum Pudding (10[1])model (10[1])in an experiment which measured the scattering (10[1])patterns (10[1])of alpha (10[1])particles. (10[1]-5[1])For (10[1])10 points, name this scientist who conducted the gold foil (10[1])experiment. (10[1])■END■ (10[3]0[1])
