Charge topology of the coherent dissociation of relativistic 11C and 12N nuclei

Abstract

The charge topology of coherent-dissociation events is presented for 11 C and 12 N nuclei of energy 1.2 A GeV per nucleon bombarding nuclear track emulsions. This topology is compared

8Be and9B nuclei in dissociation of relativistic10C and11C nuclei

“…[1], [2]]. Virtual cluster configurations in an incident nucleus are completely captured in coherent dissociation in which the target nucleus is not destroyed visibly ("white"stars).…”

“…The contribution of the unbound 8 Be and 9 B nuclei to their structure is determined on the basis of measurements of the emission angles of relativistic He and H fragments.Nuclear track emulsion (NTE) is exposed at the JINR Nuclotron to relativistic nuclei 7,9 Be, 8,10 B, 10,11 C and 12 N for the experimental study of the evolution of the cluster structure of light nuclei [reviewed in ref.[1], [2]]. Virtual cluster configurations in an incident nucleus are completely captured in coherent dissociation in which the target nucleus is not destroyed visibly ("white"stars).…”

Dissociation of relativistic 10B nuclei in nuclear track emulsion

“…Virtual nucleon associations (clusters) are the fundamental structural elements of atomic nuclei. Their simplest observable manifestations are the lightest 4,3 He and 3,2 H nuclei, which have no excited states. Superpositions of the lightest clusters and nucleons form subsequent nuclei (including unstable 8 Be and 9 B), which act as constituent clusters themselves.…”

“…The discovery of a considerable contribution of an unstable 9 B nucleus to the structure of a radioactive 10 C nucleus [3] highlighted the importance of in-depth analysis of dissociation 10 B → 2He + H. This analysis is aimed at determining the probabilities of coherent dissociation of a 10 B nucleus involving 8 Be and a 9 B nucleus. The continuation of studies into the 10 В nucleus structure was relevant to interpreting the data on 11 С, where 10 В may serve as a structural element [4].…”
