On the Coulomb corrections to the total cross section of the interaction of the π+π− atom with ordinary atoms at high energy
نویسندگان
چکیده
The size of ππ atom in the low lying states is considerably smaller than the radius of atomic screening. Due to that we can neglect this screening calculating the contribution of multi-photon exchanges. We obtain the analytic formula for Coulomb corrections which works with a very good accuracy for the ground state of ππ atom.

The Eikonal Approach to Calculation of the Multiphoton Exchange Contributions to the Total Cross Sections of Ππ Atom Interaction with Ordinary Atoms
The total cross sections of interaction of relativistic ππ 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) An accurate measurement of the ππ atom (dimesoatom) lifeti...

In the present work, the total cross-section for the ionization of H, He, Ne and Ar atoms by +He2+ ، H+ ، Li3 ions has been calculated. In these calculations, a binary encounter approximation in the form of a two-body process between projectile ions and atomic electrons at the high energy range has been implemented. In order to enter the nuclear role of the target atom, the atomic electron vel...

In fact, interactions of mono- or di-halogenated acetylenes and planar cyclooctatetraene as an anti-aromatic π system were considered. Relationship between binding energies of the complexes and charge transfer effects was investigated. Also, electronic charge density values were calc...
