摘要：
We calculate the cross section for neutralino annihilation into the two-photon and apply the cross section to find the flux in a gamma -ray telescope such as ASTROGAM. The processes <(<chi>)over tilde>(0)(1)<(<chi>)over tilde>(0)(1) --> gamma gamma may be astrophysically significant sources of gamma -ray lines. The theoretical estimates of diffuse gamma -ray background are subject to uncertainties.
