Title: HEAVY NUCLEI IN THE PRIMARY COSMIC RADIATION AT PRINCE LABERT, CANADA. I. CARBON, NITROGEN, AND OXYGEN

Abstract

A stack of G-5 emulsion, exposed at 120,000 feet for 8 hours at 61 deg N was used to study the charge and energy spectrum of heavy nuclet at the low- energy end. Energy measurements were made on C, N, and O nuclei up to 1 Bev/ nucleon. The spectrum shows a broad maximum at 550 Mev/nucleon, extrapolated to the top of the atmosphere. Various possibilities to explain this spectrum are discussed. However, it seems desirable to determine the energy spectrum of the other heavy-nuclei components in this energy region in order to gain a more complete understanding of the whole problem. Measurements of this kind are in progress and will be reported. (auth)
