We propose that an instability based on the upstream reflection and reinterception of synchrotron radiation, produced in a relativistically moving blast wave, can convert the kinetic energy of its constituent protons to an e+-e- plasma, on time scales comparable to the light crossing time of the blast wave thickness, much in the way proposed to occur in the relativistic jets of AGN. For sufficiently large values of the blast wave Lorentz factor Γ>Γc, this process can proceed without the existence of an accelerated population of protons on the shock frame. The value of Γc depends on the value of magnetic field on the blast wave frame B0 (Gauss) and it is given by Γc~600B0-1/5, in reasonable agreement with current estimates of the values of these parameters. The resulting e+-e- pairs have a Lorentz factor ~Γc and therefore produce synchrotron and IC radiation with peak emission at frequencies ~B0Γc2, B0Γc4 respectively. In in the lab frame, the IC peak emission is preceived at a frequency B0Γc5~=1 providing a possible account for the observed energy distribution of GRBs. .
