| Abstract: | A spectral approach is used to evaluate energies and widths for a wide range of singlet and triplet resonance states of helium. Data for total angular momentum L=1,…,4 is presented for resonances up to below the fifth single ionization threshold. In addition, the expectation value of cos(θ12) is given for the calculated resonances. |
