The series of H- resonances of 1Po symmetry predicted to converge exponentially to all thresholds has been investigated below the H(n=2) threshold. It is shown that the series will be terminated already after the third resonance when the relativistic and radiative splitting of the H(n=2) states is considered. Resonance parameters of this third resonance have been calculated with highly correlated wave functions. The resonance is predicted to be situated 19μeV below H(2p1/2) with a width of 0.06μeV. Accurate resonance parameters are also given for the first two resonances and the photoabsorption cross section is calculated for the threshold region.
