A nuclear interaction initiated by a proton of type 6 + l6/sub p/ was found in a nuclear emulsion flown above 110,000 fect. The angular distribution of the shower particles indicates that the primary energy was between 10 and l0/ sup 15/ ev. An unusually cnergetic electron-photon cascade was initiated which could be followed by 22.6 cm. This cascade appears to have been started by a single highenergy The effects of decaying into rays. Assuming a primary energyof 5 x 10/sup 14/ ev ( /sub c/ = 500), an energy of at least 15 Bev, in the center of mass systems would be obtained for the high-energy The effects of / sup 0/ meson.
