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. The first observations of fragmentation of GeV and nuclei in emulsion are described.

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.
