Effects of intense radiation fields on interatomic forces

The screening, by a strong radiation field, of the interatomic forces in a pair of two-level atoms is studied. The form and the intensity of these forces are obtained as functions of the detuning between the field frequency and the atomic characteristic frequency, and of the field intensity. For a particular “magic” number of radiation photons in the field, some of these interactions vanish effectively, while others are transformed in characteristic ways.
