Enhanced production of Be nuclei in relativistic nuclei fragmentation
This article is dedicated to the results of early measuring fragmentation of
relativistic O, Ne, Si, and Au nuclei in a nuclear
track emulsion. It has been found that there is a contribution of the unstable
Be nucleus decays to -particle multiplicities. These renewed
measurements of nuclear track emulsion exposed to Kr nuclei at the
energy of 950 MeV per nucleon have been analyzed and given below.Comment: To be published in PoS (PANIC2021
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 B
nucleus with target fragment accompaniment is presented. Relativistic
dissociation Be is explored using significant statistics and
a relative contribution of Be decays from 0 and 2 states is
established. Target fragment accompaniments are shown for relativistic
fragmentation N3He+H and Ne5He. 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.Comment: 15 pages, 4 figures, 4 tables, conference: Relativistic nuclear
