THE GENERATION ORDER PARAMETERS AND THE GAMMA-RAY SPECTRA OF PULSARS

Based on the Ruderman-Sutherland (or shortly R-S) model, the mechanism s of gamma-ray emission from pulsars are discussed. We mainly consider the influences of magnetic fields on photon absorption. The concept o f generation order parameters for pulsars is refined. The generation o rder parameters are proven to be monotonically and smoothly related to the spectral index and the mean photon energy. The agreement between the calculated results and the observational data is good. The radiati on conversion efficiency is also introduced. Based on these concepts, observational quantities such as luminosities, fluxes, mean photon ene rgies and others are calculated and listed in tables. Finally, we disc uss the influence of both electric and magnetic fields on the photon a bsorption.
