Antihydrogen produced in the charge transfer channel by the collision of antiprotons and positronium

In the present study, the differential and total cross sections due to the collision of antiprotons and hydrogen atoms in the charge transfer channel is calculated to form antihydrogen. The state of the incoming particles was assumed to be plane wave or Coulomb distorted wave. The impact energies of 11.3, 13.3 and 15.8 keV were assumed to be able to compare the results with the available experimental data for the total charge transfer channel. (paper)
