    "abstract": "Scattering of ortho positronium (Ps) by cesium and rubidium atoms has been\ninvestigated employing a three-Ps-state coupled-channel model with Ps(1s,2s,2p)\nstates using a time-reversal-symmetric regularized electron-exchange model\npotential. We find a narrow S-wave singlet resonance at 5.057 eV of width 0.003\neV in the Ps-Rb system and at 5.067 eV of width 0.003 eV in the Ps-Cs system.\nSinglet P-wave resonances in both systems are found at 5.3 eV of width 0.4 eV.\nSinglet D-wave structures are found at 5.4 eV in both systems. The pronounced\nP- and D-wave resonances in these systems lead to easily detectable local\nminima in the low-energy elastic cross sections. We also report results for\nelastic and Ps-excitation cross sections for Ps scattering by Rb and Cs.",
