Abstract: | The coherent repopulation of a quantum system consisting of three nonequidistant levels in the field of a resonant bichromatic
rf wave is studied. The atoms are assumed to have an impulsive interaction with the rf wave in which the pulse duration is
less than any of the relaxation times. The hyperfine structure of gas atoms and a system of atomic oscillator levels in a
magnetic trap are considered as examples of such a quantum system. It is shown that in the second case, the coherent repopulation
effect can be used to cool neutral atoms in magnetic traps.
