PARTICLE ACCELERATION IN THE “UNFAVORABLE” ZONE OF A PULSAR

Many electromagnetic phenomena on the surface of a pulsar can be explained successfully by the Arons-Scharlemann model. Yet several related phenomena have not been accounted for. In this study we provide solutions for several hitherto unsolved problems in this model, such as the mechanism for the return currents, the relationships between modes of changing and nulling of pulsars and the source for the observed cosmic ray positrons with energies greater than IGeV. In addition, we propose an explanation for the distribution of pulsar periods.
