THE EMISSION OF RADIOACTIVE NUCLEI IN COSMIC RAY STARS
Keyword(s):
It has been found that a certain proportion of the fragments emitted in cosmic ray stars formed at about 85,000 ft. consists of radioactive nuclei, i.e., in electron sensitive photographic emulsions, tracks of electrons with energies of several mega electron volts can be seen originating at the end of the track of the fragment. Details of such events are given, together with energy measurements for the disintegration electrons made by the multiple Coulomb scattering method. The significance of the results, and possible identification of the fragments, are discussed.
