Energy Determination from Multiple Meson Production by 6.3-Bev Protons in Nuclear Emulsion

Abstract

864 stars produced by the 6.3-Bev proton beam of the Berkeley Bevatron were observed in nuclear emulsion. The average number of shower particles was 2.7 prongs per star. The energy of the primary particle was determined by three different methods: (a) the median angle method; (b) Castagnoli's method; (c) Cocconi's graphical method. It is found that the results of these three methods are in good agreement with each other and are high in each case by a factor of 2.
