Soft X-ray Production By Photon Scattering From An Accreting Neutron Stars

We have calculated Compton scattering in strong magnetic fields and obtained arnfull expression of the scattering cross-section( ) of a particle, or the total area of thernscatterer as seen by the incident photons. This Scattering Cross-section is valid onlyrnfor the scattering of a low-frequency photon with non-relativistic electrons. We havernmade a plot of scattering cross-section versus incident photon frequency and tried tornsee the relationship the two parameters have got with respect to each other. Therncomparison of the incident and the scattered photon frequencies and the relationshiprnbetween the two is also shown. That is, we have tried to show that as our mechanismrnof soft x-ray production is compton scattering, the photon frequency after scatteringrnis less than its incident value. This tells us the fact that low photon frequencies arernobtained and this inturn implies the production of soft X-rays at the surface of thernneutron stars. Therefore, there exists a mechanism as a source of soft(Es < 10kev)rnradiation in binary neutron stars, in the form of photon scattering with both therninitial and final electrons on the ground magnetic states. This mechanism providesrna copious source of soft photons which can be redistributed to higher frequencies byrninverse Comptonization
