POPULATION TRAPPING IN ATOMS WITH HYPERFINE-STRUCTURE AND NUCLEAR DECAY

A new Doppler-free nuclear spectroscopy method is proposed. It is base d on the resonance interaction of bichromatic laser light with an atom with a hyperfine structure in its ground state. The population of hyp erfine components for the ii-case is calculated and the polarization r ate dependence on the laser powers and phase difference is found. The case of nonstable atoms is considered and the angular distribution of nuclear decay gamma-quanta is calculated. The problem of experimental realization of the method proposed is discussed.
