Charge Topology of the Coherent Dissociation of Relativistic C-11 and N-12 Nuclei

The charge topology of coherent-dissociation events is presented for ${}^{11}$C and ${}^{12}$N nuclei of energy 1.2~$\mathit{\text{A}}$~GeV per nucleon bombarding nuclear track emulsions. This topology is compared with respective data for ${}^7$Be, ${}^{8,10}$B, ${}^{9,10}$C and ${}^{14}$N nuclei.
