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

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(theta(12)) is given for the calculated resonances. (C) 2011 Elsevier Inc. All rights reserved.
