The chemical element nickel is of particular interest in stellar physics. In the layers in which the Fe-peak elements dominate the mean opacity (the so-called Z-bump), Ni is the second contributor to the Rosseland opacity after iron, according to the

Statistical properties of levels and lines in complex spectra: A tribute to Jacques Bauche and Claire Bauche-Arnoult

Autor: F. Gilleron, J.-C. Pain

Publikováno v: AIP Conference Proceedings.

We review recent developments of the statistical properties of complex atomic spectra, based on the pioneering work of Claire Bauche-Arnoult and Jacques Bauche. We discuss several improvements of the statistical methods (UTA, SOSA) for the modeling o

Nuclear excitation by electron transition (NEET) is predicted to be the dominant excitation process of the first $^{201}\text{Hg}$ isomeric state in a laser heated plasma. This process may occur when the energy difference between a nuclear transition

Publikováno v: Chemical Engineering Science. 58:1671-1686

Continuous food-sterilisation processes involve the flow of solid–liquid mixtures in pipes. Prediction of particle passage times in the system is required for ensuring sterility and optimising product quality. It is important to be able to predict

International audience; The X-rays emitted by a rubidium plasma source created by the PHELIX laser at an intensity of about 6×1014 W/cm2 were studied. The lines have been measured using Bragg crystals in the wavelength range between 3.8 and 7.3 Å a
