摘要：

From the radio luminosities of the cores of three globular clusters and the pulsars have been found therein, we infer that these three cores together contain less than 40 pulsars beamed towards us, for any pulsar luminosity function in a plausible range. Using various proposed models for the distribution of radio pulsars amongst globular clusters, we find an upper limit to the total number of globular-cluster pulsars of 300-700, depending on the beaming factor of these pulsars.
