Angular Distribution of Protons Inelastically Scattered from Mg²⁴

The angular distributions of protons inelastically scattered from Mg 24 ( Q =-1.368 MeV) were measured from 22.5° to 165° in the laboratory system at incident proton energies of 5.1 and 5.4 MeV. The 44'' Osaka University cyclotron was used to provide a proton beam, and the scattered protons were detected by nuclear emlusion technique. Both distributions obtained show an asymmetry about the center of mass scattering angle θ=90° and a strong dependence with the energy of primary protons.
