摘要：

Three-charge-particle collisions with participation of ultra-slow antiprotons ((p) over bar) is the subject of this work. Specifically we compute the total cross sections and corresponding thermal rates of the following three-body reactions: (p) over bar + (e(+)e(-)) -> (H) over bar + e(-) and (p) over bar + (mu(+)mu(-)) -> (H) over bar (mu) + mu(-), where e(-)(mu(-)) is an electron (muon) and e(+)(mu(+)) is a positron (antimuon) respectively, (H) over bar = ((p) over bare(+)) is an antihydrogen atom and (H) over bar (mu) = ((p) over bar mu(+)) is a muonic antihydrogen atom, i.e. a bound state of (p) over bar and mu(+). A set of two-coupled few-body Faddeev-Hahn-type (FH-type) equations is numerically solved in the framework of a modified close-coupling expansion approach.
