Extracting inter-nuclear distances in the oxygen molecule interacting with an XFEL-pulse: a fundamental system for understanding Coulomb explosion imaging
Zixu Wang, Georgios Petros Katsoulis, Giorgio Visentin +3
We investigate the interaction of O with an X-ray Free Electron laser (XFEL) pulse of short duration. We consider a photon energy of 570 eV, which allows for the formation of…

Configuration-interaction calculations with density-functional theory molecular orbitals for modeling valence- and core-excited states in molecules
Giorgio Visentin, Francois Mauger
We investigate configuration-interaction (CI) calculations on a basis of molecular orbitals generated by preliminary density-functional theory (DFT) calculations. We use this CI/DF…

Chemical Evolution of R-process Elements in Stars (CERES): IV. An observational run-up of the third r-process peak with Hf, Os, Ir, and Pt
Arthur Alencastro Puls, Jan Kuske, Camilla Juul Hansen +8
The third r-process peak (Os, Ir, Pt) is poorly understood due to observational challenges, with spectral lines located in the blue or near-ultraviolet region of stellar spectra. T…
