  Rare astrophysical events - cosmological gamma-ray bursts with energies over
GeV - are considered as an origin of information about some SUSY parameters.
The model of generation of the powerful gamma-ray bursts is proposed. According
to this model the gamma-ray burst represents as a result of the collapse and
the total annihilation of the neutralino clump. About 80 % of the clump mass
radiates during about 100 second at the final stage of annihilation. The
annihilation spectrum and its characteristic energies are calculated in the
framework of Split Higgsino model.
