摘要：

It is shown that several features of antihydrogen production in nested Penning traps can be described with accurate and efficient Monte Carlo simulations. It is found that cold deeply-bound Rydberg states of antihydrogen ((H) over bar) are produced in three-body capture in the ATRAP experiments and an additional formation mechanism-Rydberg charge transfer-, particular to the nested Penning trap geometry, is responsible for the observed fast (hot) (H) over bar atoms. Detailed description of the numerical propagation technique for following extreme close encounters is given. An analytic derivation of the power law behavior of the field ionization spectrum is provided.
