Highlights of unstable states in relativistic dissociation of light nuclei in nuclear emulsion

The results of the study of unstable states in relativistic dissociation of isotopes [Formula: see text]Be, [Formula: see text]B, [Formula: see text]C, [Formula: see text]N and [Formula: see text]O in nuclear emulsion have been summarized. Their decays are identified in distributions by invariant masses determined by fragment emission angles in the velocity conservation approximation. The observed diversity enables us to assume universality in the formation of nuclear-molecular states near the bond thresholds as a consequence of coalescence of emerging [Formula: see text]-particles and nucleons.
