The authors report highly precise numerical results of e+e- total radiative recombination cross section σ(ɛ) = Σσn(ɛ). Using a scaling law for σn(ɛ) = Σσnlj(ɛ), valid at any n and ɛ, they give analytical expressions, valid at any T, of the total recombination coefficient α. They calculate the recombination coefficients αn and the total recombination coefficient α in the temperature range of astrophysical interest. The radiative energy produced in the recombination process is also calculated.
