Fluorescence from highly excited atomic states has been observed in cesium vapor irradiated by a dye laser tuned to either one of the 62S–72P transitions. The emission originated from levels as high as 1 eV above the state being pumped. The high-lying states are believed to be excited by an electronic energy transfer induced in a collision of two atoms occupying lower excited levels.

The properties of highly excited atoms are examined. Methods for producing and detecting such atoms are analyzed. Various processes that involve atoms in Rydberg states are described, including transitions between high-lying excited states induced by collisions with electrons and atoms, quenching by electrons and atoms, ionization by collisions with electrons, atoms, and molecules, charge exchange with ions, and so on.

In principle, a possibility has been shown to excite an atom on the target level selectively and very fast with the use of high-power laser pulses. For this aim the effect of ultrafast selective excitation which was revealed earlier for vibrational levels of a molecule can be used. The example Li atom is considered. Some pulses with different frequencies should be used to excite an atom on high energy levels.
