Contribution of these processes strongly depends on the atom nucleus charge Z and varies from 1.5% for Titanium (Z=22) to 14% for Tantalum (Z=73)5 pages, LaTeX2e, 4 PostScript figureHigh Energy Physics - PhenomenologyThe eikonal approach to calculation of the multiphoton exchange contributions to the total cross sections of π^+pi^- atom interaction with ordinary atomstext
