Abstract

Peripheral interactions of12C nuclei with protons and carbon nuclei have been investigated in a 2m propane bubble chamber at 4.2 GeV/c per nucleon. Energetic and angular characteristics ofγ-quanta accompanying the production of multicharged fragments withZ f =5 and 6 have been analyzed. It is shown that in the fragment rest system there is an excess of γ-quanta with εγ<40 MeV over the background from known sources (π 0→2γ decays, bremsstrahlung and nuclear excitation).
