We consider here the spectra produced from the resonant Compton scattering of blackbody and power-law photons by a beam of relativistic electrons/positrons. The beam is assumed to be directed radially outward along the magnetic axis of a highly magnetized neutron star. We assume a dipole magnetic field geometry, and include the effects of magnetic Compton scattering energy losses on the particles in the beam during transport. A range of surface intensities for a magnetic field of 2[times]10[sup 12] Gauss is studied for a power-law electron/positron source function of index [Gamma]. The calculated scattered photon spectra are similar to observed gamma-ray burst spectra with a spectral index [alpha] which breaks from [alpha][congruent]1 to [Alpha][congruent][Gamma].
