Abstract
Neutron stars (pulsars) are here proposed as the sources of superheavy (SH) nuclei Z>or=110 in primary cosmic rays. Taking into account the 1969 result of Berlovich and Novikov that these SH nuclei can be formed by the r process when the temperature is greater than 1.8*10 degrees K and at sufficiently high neutron number density, it is here pointed out at this temperature condition can prevail in a neutron star for approximately for 103 years when the cooling behaviour is governed by the synchrotron radiation of neutrinos according to the photon-neutrino weak coupling theory. On the basis of this result, it is argued that the formation of SH nuclei in the Galaxy can be considered as a continuous event. Finally, some remarks are made about the expected flux of these SH nuclei.
