Tables have been constructed so that wave functions and energies, for any atomic state having $1s$, $2s$ and $2p$ electrons, can be computed by variational means Exchange terms are included, so that singlet and triplet states can be minimized separately By using the tables a state can be calculated in a few hours A few of the possible states have been worked out The best parameters, the total energies and the term values are given for the states $(1{s}^{2})^{1}S,(1s,2s)^{1}S,^{3}S;(1,2p)^{1}P,^{3}P; (1{s}^{2},2s)^{2}S; (1{s}^{2},2p)^{2}P; (1{s}^{2},2{s}^{2})^{1}S; (1{s}^{2},2s,2p)^{1}P,^{3}P; (1{s}^{2},2{p}^{2})^{1}S,^{1}D,^{3}P; (1{s}^{2},2{s}^{2},2p)^{2}P; (1{s}^{2},2{s}^{2},2{p}^{6})^{1}S$; of the atoms He, Li, Be, B, C, N, O, F, Ne, Na and Mg The intramultiplet separations have been computed, including the spin-spin interaction when necessary: the check with experiment being fairly satisfactory By the use of an empirical correction rule, term values can be predicted to within a few hundred wave numbersread more

TL;DR: In this article, the available theoretical values of the oscillator strengths of dipole transitions from each of the metastable states of helium are modified so that each set satisfies four different sum rules.

Structural Model of the Hydrated Electron
TL;DR: In this paper, the tetrahedron model for the electron binding in water is re-examined and the energy levels, the oscillator strength and the ESR hyperfine splitting constant of the hydrated electron have been calculated for four types of water molecules and for the various sizes of the triangulation.
