The eikonal approach to calculation of the multiphoton exchange contributions to the total cross sections of π+pi- atom interaction with ordinary atoms
Abstract
The total cross sections of interaction of relativistic π+π- atom with ordinary atoms are obtained in the eikonal approach, which takes into consideration all multiphoton exchange processes. 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)
