Wavelengths, Transition Probabilities, and Energy Levels for the Spectra of Strontium Ions (Sr II through Sr XXXVIII)

Atomic Spectral Tables for the Chandra X-ray Observatory. Part IV. NeV–NeVIII

Tables of critically compiled wavelengths, energy levels, line classifications, and transition probabilities are given for spectra of ionized neon ~Ne V–Ne VIII! in the region 55–170 Å. These tables provide data of interest for the Emission Line Project in support of analysis of astronomical data from the Chandra X-Ray Observatory. They will also be useful for the diagnostics of plasma encounte...

Energy spectra and quadrupole transition probabilities

In this paper, we have studied the energy spectra and B(E2) transition probabilities of 124-130 Ba isotopes in the shape phase transition region between the spherical and gamma unstable deformed shapes. We have used a transitional Interacting Boson Model Hamiltonian which is based on affine SU(1,1) Lie Algebra in the both IBM-1 and 2 versions and also the Catastrophe theory in combination with ...

A Critical Compilation of Energy Levels, Spectral Lines, and Transition Probabilities of Singly Ionized Silver, Ag II

All available experimental measurements of the spectrum of the Ag(+) ion are critically reviewed. Systematic shifts are removed from the measured wavelengths. The compiled list of critically evaluated wavelengths is used to derive a comprehensive list of energy levels with well-defined uncertainties. Eigenvector compositions and level designations are found in two alternate coupling schemes. So...

Determination of 137Ba Isotope Abundances in Water Samples by Inductively Coupled Plasma-optical Emission Spectrometry Combined with Least-squares Support Vector Machine Regression

A simple and rapid method for the determination of 137Ba isotope abundances in water samples by inductively coupled plasma-optical emission spectrometry (ICP-OES) coupled with least-squares support vector machine regression (LS-SVM) is reported. By evaluation of emission lines of barium, it was found that the emission line at 493.408 nm provides the best results for the determination...
