Scientific paper

It is shown that the synthesis of deuterium, He-3, and bypassed isotopes can be explained by nuclear reactions in massive supernovae of the first generation (about 10.6 billion years ago). According to the model developed, an intense shock wave arising from the supernova explosion leads to a collective acceleration of particles to relativistic energies. The interaction of these particles with atomic nuclei of the supernova shells is accompanied by fragmentation reactions with the formation of light and bypassed isotopes.
