This scientist is often mistakenly credited with Patrick Blackett’s transmutation of nitrogen to oxygen-17. A form of scattering named for this scientist was extended (-5[1])to study quarks with deep inelastic scattering. With Paul Villard, this scientist distinguished gamma rays by their penetrating power. This scientist supervised an experiment that measured scattering patterns on a fluorescent zinc sulfide screen. The Bohr model combined quantum theory (10[1])with this (-5[1])scientist’s (-5[1])model of the atom; that model included a dense, positively-charged nucleus which this scientist discovered with Geiger and Marsden. For 10 points, name (10[1])this scientist who conducted the gold foil (10[1])experiment. ■END■ (10[2])
