Abstract
In photographic emulsions exposed at 95 000 ft. the reactions of heavy nuclei (Z⩾3) with the nuclei of the emulsions have been studied. The charges and energies of the cosmic ray nuclei were determined both ‘directly’ from their multiple scattering and δ-ray densities”, or from the variation of δ-ray density with range, and ‘indirectly’ by measuring the opening angles of the showers of fragments, and the total energy released in the reactions. A survey is given of the different types of reactions observed.Keywords
