Abstract
Abstract The luminosity law of pulsars is analysed taking into account the evolution of pulsar radiation beam geometry. It is shown that, if the observed luminosity is not corrected for the geometrical factor, we obtain very high luminosities for some evolved pulsars, even higher than in some young ones. Such a correction makes PSR J0218+4232, claimed to be a very luminuous pulsar (Navarro et al., 1995) an ordinary object among pulsars. This incorrect estimation of luminosities also leads to the apparent flattening of the luminosity law of pulsars.
