In laser isotope separation based on polarization selection rules the effect of magnetic field on isotopic selectivity was investigated. Excitation dynamics of atoms by linearly polarized lasers were numerically analyzed for J equals 2 yields 2 yields 1 yields 0 stepwise excitation under a magnetic field. Time evolution of the population in each magnetic substrate was calculated by solving the rate equations under the condition in which the atomic alignment is gradually destroyed by precession motion of the angular momentum around a magnetic field. It was found that a relatively small magnetic field may cause a selectivity loss and the field strength component perpendicular to laser polarization direction should be kept as small as the terrestrial magnetic field to obtain a high selectivity in the case of gadolinium isotope separation.
