The relativistic invariant approach is applied to analyzing the
GeV
fragmentation in a nuclear track emulsion. New results on few body
dissociations are obtained from the emulsion exposures to
GeV
and
GeV
nuclei. It can be asserted that the use of the invariant
approach is an effective mean of obtaining conclusions about the behavior of
systems involving a few He nuclei at a relative energy close to
MeV per
nucleon. The observations allow one to justify the development of few body
aspects of nuclear astrophysics.
