RESEARCH ARTICLE An algebraic approach to the comparative study of the vibrational spectra of monofluoroacetylene (HCCF) and deuterated acetylene (HCCD)
TL;DR: Using the Lie algebraic method, the vibrational energy levels of HCCF and HCCD were calculated for 102 and 110 vibrational bands, respectively, using the local Hamiltonian.

Calculations for 1s23l3l' states in C2+, N3+, O4+, Ne6+ and Xe50+
Nathalie Vaeck,Jørgen E. Hansen +1 more
TL;DR: In this article, the authors presented energy level values, radiative transition probabilities and autoionisation rates for terms belonging to the 1s23l3l' configurations for several ions in the Be I isoelectronic sequence (C2+, N3+, O4+, Ne6+ and Xe50+).

How good is Niels Bohr's atomic model?
TL;DR: The history and evidence for these two extreme paradigms are presented and some of the potentially observable consequences are discussed briefly in this article, where the authors discuss the potential consequences of the collective quantization of atomic valence shells containing two electrons.

On a screening theory of atomic spectra
TL;DR: In this article, a theoretical scheme for describing atomic spectra is developed, which differs from the current one in three main ways: (i) the nuclear charge Z enters explicitly into all predictions made with the new scheme, and (ii) certain effects of configuration interaction are allowed for in the first approximation.

Wigner Coefficients for the R4 Group and Some Applications
TL;DR: In this article, the R4 spherical harmonics and their properties are obtained as specializations of the general formulas, and their physical application to the problem of geometrizing the Coulomb field is briefly discussed.
