Abstract：
The cross section of the process X-0X-0→gg is calculated in supersymmetry model of parti- cle physics. By means of the obtained cross section value, the estimate of source spectrum for anti- protons produced by neutralino X-0 annihilation is given. We conclude that the observation of this spectrum in the low energy region offers a possible approach to find the dark matter and the super- symmetry particle.
