Clustering in relativistic dissociation of ${}^9$be, ${}^9$c, ${}^{10}$c and ${}^{12}$n nuclei

Abstract

The dissociation features in nuclear track emulsion of ${}^9$Be, ${}^{9,10}$C, and ${}^{12}$N nuclei of 1.2 A GeV energy are presented. The data presented for the nucleus ${}^9$Be can be considered as evidence that there is a core in its structure in the form of 0${}^{+}$ and 2${}^{+}$ states of the ${}^8$Be nucleus having roughly equal weights. Events of coherent dissociation ${}^9$C$\to 3^3$He associated with the rearrangement of the nucleons outside the $\alpha$-clustering are identified. A pattern of the charge fragment topology in the dissociation of ${}^{10}$C and ${}^{12}$N nuclei is obtained for the first time. Contribution of the unbound nucleus decays to the cascade process ${}^{10}$C${\to }^9$B${\to }^8$Be is identified.
