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 magnitized 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 are studied for a power-law electron/positron source functions 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} {approx equal} 1 to {alpha} {approx equal} {Gamma}.
