    "abstract": "Effect of charge-transfer recombination for positronium (Ps) scattering is\nstudied on Ps-H system using coupled-channel formalism considering a new\nrearrangement channel Ps+H --\u003e e^+ + H^- and exchange.\n  The correlation and continuum effects introduced by this charge-transfer\nchannel result to substantial convergence to the low energy scattering\nparameters. Effects on scattering length, PsH binding energy, and low-energy\n(0-10 eV) phase-shifts and cross sections are evaluated and H$^-$ formation\ncross sections are reported from above the threshold (6.438 eV) to 100 eV.",
