摘要：

We study theoretically the formation of positronium atoms through electron capture in collisions of positrons impacting on hydrogenlike targets such as He+, Li2+, and Be3+. We obtain the scattering amplitude of the charge-exchange process by using a distorted-wave model derived from the first order of a Dodd and Greider's expansion. We compute differential and total cross sections by using a partial-wave technique.
