Abstract
The modified Faddeev equations are used to calculate the complete multichannel K matrices within the energy gap between the $\mathrm{Ps}(n=1)$ and $\mathrm{Ps}(n=2)$ thresholds. We report here a number of partial cross sections in this energy range including hydrogen production cross sections in the Ps entrance channel. The angular momentum states calculated are S, P, D, and F states. The number of open channels ranges from two in the Ore gap to four and five above the $\mathrm{H}(n=2)$ threshold. Comparison with previous calculations is made whenever feasible. Agreement within a few percentages is observed for most cases.
