    "abstract": "Scattering of positronium (Ps) by helium atom has been investigated in a\nthree-Ps-state coupled-channel model including Ps(1s,2s,2p) states using a\nrecently proposed time-reversal-symmetric regularized electron-exchange model\npotential. Specifically, we report results of differential cross sections for\nelastic scattering and target-elastic Ps excitations. We also present results\nfor total and different partial cross sections and compare them with experiment\nand other calculations.",
