Coherent dissociation of relativistic 9Cnuclei in nuclear track emulsion

For the first time nuclear track emulsion is exposed to relativistic 9 C nuclei. A systematic pattern of the distributions of charge combinations of fragments in the peripheral interactions of 9 C nuclei in a nuclear track emulsion has been obtained. The main conclusion is that the contribution of the channel 9 C → 8 B + p and 9 C → 7 Be +2 p is most important in events that do not involve the production of target‐nucleus fragments or mesons (coherent dissociation). It can be concluded that in the peripheral 9 C dissociation the picture hitherto obtained for 8 B and 7 Be with the addition of one or two protons, respectively, is reproduced. Three coherent dissociation events 9 C →3 3 He accompanied by neither target fragments of the nucleus target nor charged mesons are identified.
