Fragmentation of relativistic $^{10}$C radioactive nuclei in a track nuclear emulsion

The charge topology in the fragmentation of 10 C nuclei in a track nuclear emulsion at an energy of 1.2 GeV per nucleon is studied. In the coherent dissociation of 10 C nuclei, about 82% of events are associated with the channel 10 C 2+ 2p. The angular distributions and correlations of product fragments are presented for this channel. It is found that among 10 C 2+ 2p events, about 30% are associated with the process in which dissociation through the ground state of the unstable 9 Be g.s. nucleus is followed by 8 Be g.s. + p decays.
