    "abstract": "The low-energy scattering of ortho positronium (Ps) by H, He, Ne, and Ar\natoms has been investigated in the coupled-channel framework by using a\nrecently proposed time-reversal-symmetric nonlocal electron-exchange model\npotential with a single parameter $C$. For H and He we use a three-Ps-state\ncoupled-channel model and for Ar and Ne we use a static-exchange model. The\nsensitivity of the results is studied with respect to the parameter $C$.\nPresent low-energy cross sections for He, Ne and Ar are in good agreement with\nexperiment.",
