Fragmentation of relativistic nuclei in peripheral interactions in nuclear track emulsion
The technique of nuclear track emulsions is used to explore the fragmentation of light relativistic nuclei down to the most peripheral interactions - nuclear "white" stars. A complete pattern of therelativistic dissociation of a \(^8\)B nucleus with target fragment accompaniment is present...

| description | The technique of nuclear track emulsions is used to explore the fragmentation of light relativistic nuclei down to the most peripheral interactions - nuclear "white" stars. A complete pattern of therelativistic dissociation of a \(^8\)B nucleus with target fragment accompaniment is presented. Relativistic dissociation \(^{9}\)Be\(\to2\alpha\) is explored using significant statistics and a relative contribution of \(^{8}\)Be decays from 0\(^+\) and 2\(^+\) states is established. Target fragment accompaniments are shown for relativistic fragmentation \(^{14}\)N\(\to\)3He+H and \(^{22}\)Ne\(\to\)5He. The leading role of the electromagnetic dissociation on heavy nuclei with respect to break-ups on target protons is demonstrated in all these cases. It is possible to conclude that the peripheral dissociation of relativistic nuclei in nuclear track emulsion is a unique tool to study many-body systems composed of lightest nuclei and nucleons in the energy scale relevant for nuclear astrophysics. |
