Phys. Rev. A 71, 052717 (2005) [6 pages]Protonium formation in antiproton–hydrogen-atom collisionsReceived 10 November 2004; published 31 May 2005 Expressions for momentum distributions of electrons in antiproton–hydrogen-atom collisions are derived in the framework of the advanced adiabatic approach for the time- independent Schrödinger equation. Protonium formation cross sections for states with different n and l spherical quantum numbers are also obtained. Total ionization and protonium formation cross sections are compared with other calculations in the interval of impact energies from 0.5 eV to 10 keV. We show that diabatic states promoted into the continuum can be rigorously defined within the advanced adiabatic framework. © 2005 The American Physical Society URL:
