p Elastic and Charge Exchange Scattering at About 120 MeV
Phys. Rev. 110 (1958) 994;

Summary
We have observed 478 antiprotons entering the chamber. One such event is shown. The complete analysis of these events is in progress; however, a preliminary report on the p elastic scattering is now available. A total of 33 p elastic collisions have been observed over a path length of 179 meters. The scatterings occur between 30 and 215 MeV with an average energy of 120 MeV. Only -p scatterings with angles > 7.5 (lab) were identifiable because otherwise the energy of the recoil proton was too small to make a visible track, so that these scatterings are indistinguishable from C. (Extracted from the introductory part of the paper.).
