Measurement of the isotopic composition of the primary cosmic radiation for the elements B-Ne

Description

The results are given from an investigation of the isotopic composition of primary cosmic ray B, C, N and O. Preliminary result is also given from an investigation of Ne. The mass measurements are made in nuclear emulsions exposed at about 3 g/cm2 atmospheric depth. The results for B-O represented as quotients extrapolated to the top of the atmosphere, are: 11B/B=0.61+-0.10; 13C/C=0.06+-0.03; 15N/N=0.33+-0.09; 17O/O=0.05+-0.03; 18O/O=0.08+-0.03. The preliminary result from the Ne-measurements shows that nuclei with masses larger than 20 exist among the primary neon nuclei. (Auth.)
