Phys. Rev. A 59, 4732–4735 (1999)Electromagnetically induced absorptionReceived 11 September 1998; published in the issue dated June 1999 A large increase in atomic absorption due to coherent interaction with resonant radiation is predicted for a closed transition between two degenerate atomic levels verifying 0<Fg<Fe(Fg and Fe are the total angular momentum of the ground and the excited levels, respectively). In good agreement with the theoretical prediction, a total absorption enhancement by a factor 1.7 was obtained on the D2 line of 85Rb in a vapor cell experiment. © 1999 The American Physical Society URL:
