- Title
Energetic electronic ensembles: new rules for the interaction of radiation with matter.

- Abstract
Abstract. The fundamental problem of the interaction of radiation with matter is considered for light intensities considerably larger than an atomic unit. By using intense femtosecond pulses in the UV spectral range, the coupling of radiation to matter is substantially modified. The usual weak coupling behavior characterized by the fine-structure constant alpha = 1/137 has to be replaced by Z[sup 2]alpha, where Z is the number of cooperatively acting electrons, which leads to anomalously strong coupling between radiation and matter.
