ANTIPROTON INTERACTIONS IN HYDROGEN AND CARBON BELOW 200 Mev (thesis)
About 500 antiprotons in a partially purified beam were observed to enter the 30-in. propane bubble chamber. An arrangement of time-of-flight scintillation counters and a velocity-selecting counter enabled electronic identification of antiproton events, thus reducing scanning to a minimum and also providing a sample of antiprotons free of scanning bias. The antiprotons entered the propane at a kinetic energy of 220 Mev and were brought to rest. Scattering and anninilation intera tions in both hydrogen and carbon were observed vs. antiproton energy. Differential scattering cross sections were obtained, and the total cross sections were meassured for antiproton km. etic energies in the ranges 75 to 137.5 Mev and 137.5 to 200 Mev. (auth)
