Abstract
The physics of elementary atoms, i.e., Coulomb bound states such as positronium, pionium, etc., is briefly presented. The formulas for cross sections of elementary-atom interactions with an external field are evaluated in the nonrelativistic and Born approximations. The numerical calculations of the total, elastic, and excitation cross sections are performed for seven elementary atoms and five typical targets. Atomic form factors are discussed in detail.
