The determination of nuclear moments from the angular distribution of radiation emitted by dynamically polarized nuclei

A method is suggested which allows the establishment both of the sign and magnitude of quadrupole interaction and the magnitude of magnetic moment of radioactive nuclei. The dynamic polarization of these nuclei is assumed (by means of the effet solide or the method of Jeffries) as well as the subsequent change of the degree of orientation (by means of saturation of some suitable nuclear transitions). The comparison of resonant frequencies for negative and positive initial polarization gives the values of the above-mentioned quantities. The angular distribution of the intensity of radiation emitted is used for the detection of changes in the degree of polarization.
