摘要The process of inverse Compton scattering (ICS) of high-energy particles off the thermal photons above the pulsar polar cap is the dominant mechanism causing polar gap breakdown. In this paper, an approximate analytic description of the parameters of the two modes of the ICS gap, namely, the "resonant ICS gap" and the "thermal ICS gap," are derived under the assumption of a multipolar magnetic field configuration in the neutron star's vicinity. For typical values of P, B, and T, the thermal ICS gap usually has a lower height and smaller potential drop but results in larger Lorentz factors for the secondary particles ejected from the gap.
