• A two-body bound state equation for a positron and an electron in an interacting electron gas is rederived, using a Green's function decoupling scheme and various approximations required to define a bound state are explained. The equation has some new features not discussed before, and the solution rules out the formation of positronium-like state at metallic densities. But the critical r_s-value where the bound state formation starts is found to be higher than previously reported.
