Abstract A study is made of the isotopic composition of primary cosmic ray boron and carbon in the energy interval 135–390 MeV/n. The quotients11B/(10B +11B) = 0.61 ±0.12 and13C/(12C +13C) = 0.06 ±0.04, valid at the top of the atmosphere, are obtained from photometric measurements on tracks found in an Ilford G5 emulsion stack exposed to the radiation.
