The cross section of the process <(<chi>)over tilde>(o)<(<chi>)over tilde>(
o)-->gg is calculated in supersymmetry model of particle physics. By means
of the obtained cross section value, the estimate of source spectrum for an
tiprotons produced by neutralino <(<chi>)over tilde>(o) annihilation is giv
en. We conclude that the observation of this spectrum in the low energy reg
ion offers a possible approach to find the dark matter and the supersymmetr
y particle.
