    "abstract": "We assume all interaction to be Coulombic and solve the modified Faddeev\nequation for energies between the $Ps(n=2)$ and $\\bar{H}(n=3)$, which involve\nsix and eight open channels. We find that 99% of the antihydrogen are formed in\n$\\bar{H}(n=2)$. Just above the $Ps(n=2)$ threshold the S, P, and D partial\nwaves contribute more than 4000 square Bohr radii near the maximum. Evidences\nindicate that the induced long range dipole potential from the degenerate\n$Ps(n=2)$ targets is responsible for such a large antihydrogen formation cross\nsection.",
