The Mechanism of Component Formation out of the Main Pulse of a Radio Pulsar. II. The Interpulse

Abstract

The theory of induced scattering off the ultrarelativistic particles in a moderately strong magnetic field is developed. The kinetic equations obtained are applied to the problem of induced scattering of pulsar radiation out of the narrow beam. It is shown that the scattered radiation predominantly concentrates in the direction antiparallel to the velocity of the scattering particles. Based on this process, we for the first time suggest a physical mechanism of the interpulse component of a pulsar. Our model explains the observed spectral and polarization peculiarities of the interpulse emission as well as its connection to the main pulse.
