Spectral data for doubly excited states of helium with non-zero total angular momentum

preprint2011arXivOpen access

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,...,4L=1,...,4 is presented for resonances up to below the 5th single ionization threshold. In addition the expectation value of cos⁡(θ12)\cos(θ_{12}) is given for the calculated resonances.
