A Possible Source of Cosmic Rays From A Burst In The Centre Of Galaxy

Considering the spectral energy of the observed cosmic rays in the earth and using a propagational model of these rays, the minimum required energy for production of these rays in the center of galaxy studied. Assuming an equation for the time scape from the galaxy and a relation for their diffusion, calculations show that the centeral part of the galaxy, the most energetic part of the galaxy, does not have the necessary conditions to produce all these rays. But the centre of the galaxy has the possibility to produce energy range between 3*10^15 to 4*10^18 eV.The spectral energy of this energy is suggested to be B E^-2.9 cm^-2 s^-1 sr^-1 eV^-1.
