Abstract
Status and prospects of nuclear clustering studies by dissociation of relativistic nuclei in nuclear track emulsion are presented. The unstable 8Be and 9B nuclei are identified in dissociation of the isotopes 9Be, 10B, 10C and nC, and the Hoyle state in the cases 12C and 16O. On this ground searching for the Hoyle state and more complex α-particle states in the dissociation of the heavier nuclei is suggested. A detailed study of a low-density baryonic matter arising in dissociation of the heaviest nuclei is forthcoming long-term problem. An analysis of nuclear fragmentation induced by relativistic muons is proposed to examine the mechanism dissociation.
Highlights
Theories of the matter arising due to nucleon clustering in the lightest nuclei under conditions of a lowest baryonic density [1] and α-particle BoseEinstein condensate [2] have been developed
Relevant ensembles can be studied in dissociation of relativistic nuclei in a nuclear track emulsion (NTE)
Necessary measurements of emission angles of relativistic fragments H and He and their identification by the multiple scattering are accessible in NTE only
Summary
Theories of the matter arising due to nucleon clustering in the lightest nuclei under conditions of a lowest baryonic density [1] and α-particle BoseEinstein condensate [2] have been developed. Relevant ensembles can be studied in dissociation of relativistic nuclei in a nuclear track emulsion (NTE) (review [3]). Reconstruction of the invariant mass of relativistic decays of the unstable nuclei 8Be and 9B confirms this approximation and allows establishing their contribution to the dissociation pattern.
