The interaction of 1.0, 1.25, and 2.0 Bev antiprotons with protons was studied with the aid of a 4 pi solid-angle scintillation-counter detector system. The measured total cross sections at the above energies were 100, 89, and 80 mb, respectively. At each energy, the charge-exchange cross section was approximately 5 mb. The total elastic cross sections were 33, 28, and 25 mb, respectively, at the three energies. The angular distribution of elastic scattering was fitted with a simple optical-model calculation.
