Resonant excitation of hyperfine levels in a bichromatic laser wave in connection with nuclear decay
A new nuclear-spectroscopy method is proposed. It is based on a resonant interaction of an atom which has hyperfine structure in its ground state with the field of a bichromatic laser wave. The method is essentially free of Doppler-broadening effects. The model of а Λ system is used to derive expressions for the time evolution of the populations of the hyperfine components and for the behavior of the angular polarization of the emission from the nuclear decay as a function of the relations between the strengths and phases of the fields in the bichromatic wave. Ways to implement this method experimentally are proposed. © 1994 American Institute of Physics.
