Even-parity 1p resonances of H- up to the n=5 threshold

We report highly accurate results of ab initio calculations of the energies, widths, wavefunction characteristics and spectral trends of 22 hitherto unknown H- resonances of P-1 symmetry up to the n = 5 threshold, using as the cut-off criterion states with widths down to about 1 x 10(-10) au. Classification into series according to spectral trends below the n = 3, 4 and 5 thresholds shows that in the latter case two series are formed for which the regularity expected from the Gailitis-Damburg model of dipole resonances is perturbed by interseries interaction. No shape resonance exists in this energy range.
