We report on electromagnetically induced transparency in a radio-frequency discharge of metastable helium atoms. We show that a large effect can be observed in spite of the discharge regime needed to produce the metastable helium and in spite of its Zeeman degeneracy. We discuss the mechanism and the conditions for the observation of such a phenomenon in a helium discharge.

Abstract
We report on electromagnetically induced transparency in a radio-frequency discharge of metastable helium atoms. We show that a large effect can be observed in spite of the discharge regime needed to produce the metastable helium and in spite of its Zeeman degeneracy. We discuss the mechanism and the conditions for the observation of such a phenomenon in a helium discharge.File in questo prodotto:
