Synchrotron emission from the depths of pulsar magnetospheres

In this paper we study the generation of high energy emission from normal pulsars. For this purpose we consider the particles accelerated in the outer magnetosphere sliding along the closed magnetic field lines. It has been shown that in due course of motion the initial small pitch angle increases and at a certain distance from the neutron star the synchrotron emission becomes significant. We found that in a region covered from 150 to 500 stellar radii the emission pattern is characterised by energies in the interval ( 0.1 − 10 ) MeV.
