摘要：

Steep dispersion of opposite signs in driven degenerate two-level atomic transitions have been predicted and observed on the D-2 line of Rb-87 in an optically thin vapor cell. The intensity dependence of the anomalous dispersion has been studied. The maximum observed value of anomalous dispersion (dn/d nu similar or equal to -6 x 10(-11) Hz(-1)) corresponds to a negative group velocity V-g similar or equal to -c/23 000.
