Numerical Results and Discussion

This chapter provides a comparative discussion of the numerical results for the radiative and nonradiative attachment mechanisms under consideration. In this context, we also briefly discuss the efficiency of positron capture in collisions of positronium with antihydrogen. Further, we discuss the role of annihilation and other processes related to the interaction between matter and antimatter for two-center dileptonic and electron-assisted three-body attachment, both in which matter particles are involved.
