Particle Production at Large Angles by 30- and 33-Bev Protons Incident on Aluminum and Beryllium

A mass analysis has been made of the relatively low momentum particles emitted from Al and Be targets when struck by 30- and 33-Bev protons. Measurements were made at 90^∘{}, 45^∘{}, and 13{}^∘{} relative to the direction of the Brookhaven AGS proton beam. Magnetic deflection and time-of-flight technique were used to determine the mass of the particles.
