Abstract

A new method for determining the accelerating potential above the polar caps of radio pulsars with an arbitrary inclination angle of the magnetic axis to the rotation axis is proposed. The approach is based on the concept of a vacuum gap, the height and shape of the upper boundary of which are found self-consistently together with the solution of the corresponding Poisson equation. In turn, knowledge of the accelerating potential allows one to determine the transverse profiles of the secondary plasma density. It is also shown that the influence of inverse Compton scattering on the processes under consideration is insignificant.
