| Abstract Various geometrical and energetical (bound-state) properties of the positronium negative ion (Ps- or e-e+e-) are determined by using highly accurate variational wave functions. These wave functions have been constructed by applying the advanced two-stage strategy proposed by Frolov [Phys. Rev. A 57, 2436 (1998)]. The determined total energy of the ground state E=-0.262 005 070 232 975 7 a.u. is the lowest and most accurate value obtained for this system to date (the corresponding binding energy equals -0.326 674 721 317 821 eV). The computation of the second-order relativistic corrections (??2) to the total energy is discussed also. The general form of the Breit-Pauli Hamiltonian in the relative coordinates for the Ps- ion is presented. |
