The Radio Luminosity of Pulsars and the Distribution of Interstellar Electron Density
The radio luminosities of pulsars are given as functions of their period and the timevariation of the period. The parameters of that dependence are calculated and independent distancesare determined for pulsars. The average electron densities toward the pulsars are determined from theknown dispersion measures. The results obtained are used to study the large-scale electron densitydistribution in the Galaxy. The distribution maximum lies in the vicinity of the Sagittarius spiral arm.The electron density falls otf exponentially in the regions between spiral arms.
