Abstract
The anomalous dispersion is used i n the present work for atomic spectral analysis. A Michelson ir~terLerometer containing the absorbing atorus i n one of its arms is combined vdth a low- powr grating spectrograph.

The c h a r a c t e r i s t i c s of these functions are studled from the spectroscopic point of view.
