Abstract:UCRL-8279In a scintillation-counter experiment the interaction of antiprotons with protons in the energy region 133 to 333 Mev has been studied. Antiprotons, produced internally in 'the Bevatron, channeled externally by a system of magnetic quadrupoles and bending magnets, and identified by time of flight, entered a tar get containing liquid hydrogen. This target was completely surrounded by a system of scintillation counters which detected both scattered antiprotons and annihilation .secondaries. An electrost… Show more

“…Our results show support for the Ball-Chew theory on p scattering and annihilation, within the validity of our statistics. It should be pointed out that a recent counter experiment, 9 as well as accumulated emulsion results, 15 also lend verification to the theory. -6-The annihilation process is especially adapted to bubble chamber observation.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
