Double well Stark effect: Crossing and anticrossing of resonances

The author reviews experimental techniques which use the properties of the scattering of light by free atoms in the neighborhood of a resonant frequency for investigation of excited atomic energy levels : - Hanle effect and its recent developments : (Hanle effect in an electrostatic field, molecular Hanle effect, Hanle effect of stepwise excited levels, sensitized fluorescence Hanle effect). - Double resonance experiments and its variations (« light beats »), excitation with modulated light...). - Level crossings and anticrossings (including of the study Stark effect by level crossings).The author reviews experimental techniques which use the properties of the scattering of light by free atoms in the neighborhood of a resonant frequency for investigation of excited atomic energy levels : - Hanle effect and its recent developments : (Hanle effect in an electrostatic field, molecular Hanle effect, Hanle effect of stepwise excited levels, sensitized fluorescence Hanle effect). - Double resonance experiments and its variations (« light beats »), excitation with modulated light...). - Level crossings and anticrossings (including of the study Stark effect by level crossings).

Anticrossing Spectroscopy of Rydberg Atoms Using Blackbody Radiation

R. C. Stoneman, Thomas F. Gallagher

We report the observation of anticrossing signals arising from the interaction of 300-K blackbody radiation with Rydberg atoms near avoided crossings of Stark levels. The role of the blackbody radiation is roughly analogous to that of the resonance fluorescence in traditional anticrossing spectroscopy. We present preliminary results for avoided crossings of $\mathrm{ns}$ states with $n\ensuremath{-}2$ Stark states in potassium for $n$ in the range 18-21.We report the observation of anticrossing signals arising from the interaction of 300-K blackbody radiation with Rydberg atoms near avoided crossings of Stark levels.
