Spectral data for doubly excited states of helium with non-zero total angular momentum
J Eiglsperger, M Schönwetter, B Piraux… - Atomic Data and Nuclear …, 2012 - Elsevier
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 (θ 12) is given for the calculated resonances.
