    "abstract": "The temporal evolutions of coherent resonances corresponding to\nelectromagnetically induced transparency (EIT) and absorption (EIA) were\nobserved in a Hanle absorption experiment carried on the $D_{2}$ lines of $%\n^{87}$Rb vapor by suddenly turning the magnetic field on or off. The main\nfeatures of the experimental observations are well reproduced by a theoretical\nmodel based on Bloch equation where the atomic level degeneracy has been fully\naccounted for. Similar (opposite phase) evolutions were observed at low optical\nfield intensities for Hanle/EIT or Hanle/EIA resonances. Unlike the Hanle/EIA\\\ntransients which are increasingly shorter for driving field intensities\napproaching saturation, the $B\\neq 0$ transient of the Hanle/EIT signal at\nlarge driving field intensities present a long decay time approaching the\natomic transit time. Such counterintuitive behavior is interpreted as a\nconsequence of the Zeno effect.",
