It is found that impurity beta-active nuclei 8Li in LiF undergo resonant depolarization not only when the specimen is irradiated by a radio-frequency field, rotating with the Larmor frequency of 8Li, but also at frequencies that are linear combinations of the Larmor frequencies of 8Li, 7Li, and 19F with integer coefficients. The frequencies, forbiddenness parameters, and second moments of the resonances are measured.
