We investigate the change of shape of the Zeeman absorption line and of the dispersion of cadmium vapor under the influence of resonant and quasiresonant radiation. The theoretically predicted reversal of the sign of the absorption coefficient of a two-level system under the influence of a powerful monochromatic radiation without production of population inversion is confirmed.
