Abstract
The photoproduction of a neutrino pair on a nucleus, \(\gamma+ Ze \to {\rm Z}e + \gamma+ \nu+ \bar \nu \), is investigated in a strong magnetic field. It is shown that taking account of the photon dispersion in a strong field reduces appreciably the catalyzing effect of the latter on the process. Therefore, at any field magnitude, neutrino photoproduction cannot compete with the Urca processes. This conclusion contradicts a recent statement in the literature.
