Energy requirements in human beings,The general structure of atomic spectra in the different groups of the periodic table is reviewed in the framework of isoelectronic sequences, and the present state of the analysis in indicated for sequences of 3- to 46-electron systems. A list of references to recent term analyses has been compiled for the elements from Z=2(He) to 28(Ni).

https://doi.org/10.1007/978-3-540-70974-9We have reviewed the literature for measurements of the lifetimes of excited states of the first few spectra of the third and fourth period elements. In this paper we present our results for the third period elements. Results for the fourth period are to be presented in the following paper.

Correlation Effects and F-Values in the Sodium Sequence,The simplest atomic system in which nℓ electrons interact with a 1s.2s.2p. core are the sodium iso-electronic sequences for states 1s.2s.2p.nℓ, n ≥ 3. The spectra for these atoms and ions are traditionally treated as one-electron spectra, implying little or no correlation with the core.
