摘要：

Low-energy elastic scattering of electrons from the ground state of positronium atoms embedded in weakly-coupled plasmas has been studied within the framework of an effective range theory. Plasma screening effect has been taken care of by screened Coulomb potential. Highly correlated and variationally determined wave functions for Ps(-) are used to determine the effective range of the ion states. The results for S-wave singlet phase shifts for the incident electron momentum in the range of [0, 0.5] a.u. are reported, to the best of our knowledge, for the first time in the literature.
