Comparison of Pion- and Proton-Production of Charmonium
… (pi)-beryllium interactions at 190 Gev/c and in proton-beryllium interactions at 200 Gev/c and 250 Gev/c have been observed via their decay into J/(PSI)+(gamma). This experiment was carried out with the Chicago Cyclotron Magnet Spectrometer at Fermilab. The fraction of J/(PSI)'s resulting from …

Production of helium and neon in the lunar regolith by solar cosmic ray protons
… were bombarded with 1 to 1 intermediate energy protons (15 to 45 MeV) in order to determine He, Ne, and Ar production cross sections. This energy range was selected because it represents a significant portion of the solar cosmic ray (SCR) spectrum. Certain radioactivities were measured by Dr. …
