The cosmic ray boron and carbon isotopic composition measured in nuclear emulsions

  • 1. Lund Univ. (Sweden). Dept. of Physics

Description

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