The relaxation time of nuclei in semiconductors or semimetals in a magnetic field of such intensity that the quantization of electron space motion becomes essential, is calculated. Cases of nondegenerate and strongly degenerate carrier gas are studied. Relaxation is presumed to occur at the expense of contact interaction of nuclear spins with conduction electrons. It is supposed that the energy zones possess the isotropic quadratic law of dispersion. The presence of peaks in transition probability is established. These peaks are more strongly expressed when a small quantity of Landau subzones is populated. In a number of cases these peaks form two series.
