A new type of nuclear scattering camera utilizing photographic emulsions to determine number and energy of scattered protons at many sharply defined angles is described and compared with earlier experimental arrangements. A survey of the effects of various factors in producing straggling of the scattered particles is presented. The angular distributions of elastically and inelastically scattered proton groups are presented, and the former compared with Rutherford scattering. Excited states of magnesium nuclei are found to occur at 1.37 Mev, 2.80 Mev, and 4.07 Mev.
