THE DETECTION OF ABERRATION AND RETARDATION EFFECTS IN THE PULSAR B0329+54

A shift of the symmetry axis of the main conal components relative to the central component was discovered in the mean profile of PSR B032954; this shift increases with decreasing frequency. This effect is acc ounted for by the combined influence of aberration and retardation, an d is related to the difference Delta r similar to 10(8) cm in the leve ls where the emission at 103 and 10 700 MHz is formed. The conal compo nents are generated r similar to 10(9) cm from the center of the neutr on star by the Cerenkov resonance, while the cyclotron mechanism is re sponsible for the formation of the central component in deeper layers of the magnetosphere (r similar to 10(8) cm).
