Photoionization of Ar XVI and Ar XVII

Photoionization of Li-like argon, ðhnþAr XVI-Ar XVIIþeÞ, and He-like argon, ðhnþ Ar XVII-Ar XVIIIþeÞ, are studied using the relativistic Breit–Pauli R-matrix (BPRM) method. Results include both the partial and total photoionization cross-sections of fine structure levels with 1=2r Jr17=2, nr10 and 0r lr9 of Ar XVI and with 0r Jr10, nr10 and 0r lr9 of Ar XVII. They correspond to 98 bound levels ...

Integrated analytical study for the authentication of five Russian icons (XVI-XVII centuries).

This article presents an integrated approach for the authentication of five Russian icons through the study of their paint materials (elemental composition and stratigraphic mapping), state of conservation and artistic technique. The results of the applied analytical protocol, involving optical and scanning electron microscopy coupled with energy-dispersive X-ray spectrometry and Fourier transf...

Using a new dataset, this paper presents new evidence on inequality in Latin America for the 19th century and studies the effects of factor endowments and trade on inequality. Recent research has highlighted the link between the colonial origins of inequality and its persistence in Latin America. We find that inequality varied substantially throughout the century a...

Photoionization cross sections for Fe XVI and Fe XVII recombination rate coefficients

The Breit-Pauli R-matrix codes are utilized in a detailed study of the photoionization of the ground state of Fe XVI (2s22p63s S1/2). High resolution total and partial cross sections are obtained using 37 Jπ configuration interaction type wavefunctions to represent the residual ion, Fe XVII, after 3s, 2p and 2s photoionization. For the total cross section, the work of Verner et al. and previous...
