Electronic structure and photoluminescence properties of Eu(η9-C9H9)2

Ramanantoanina, Harry ; Merzoud, Lynda ; Muya, Jules Tshishimbi ; Chermette, Henry ; Daul, Claude

In: The Journal of Physical Chemistry A, 2020, vol. 124, no. 1, p. 152–164

The electronic structure of Eu2+ compounds results from a complex combination of strongly correlated electrons and relativistic effects as well as weak ligand–field interaction. There is tremendous interest in calculating the electronic structure as nowadays the Eu2+ ion is becoming more and more crucial, for instance, in lighting technologies. Recently, interest in semiempirical methods to...

Coupling of electronic and nuclear motion in a negative ion resonance: Experimental and theoretical study of benzene

Allan, Michael ; Čurík, Roman ; Čársky, Petr

In: The Journal of Chemical Physics, 2019, vol. 151, no. 6, p. 064119

We present calculated and measured elastic and vibrational excitation cross sections in benzene with the objective to assess the reliability of the theoretical method and to shed more light on how the electronic motion of the incoming electron is coupled with the nuclear motion of the vibrations. The calculation employed the discrete momentum representation method which involves solving the...

Laboratory based XAS measurements, electron-induced double K-shell ionization of Sc, Cr and Cu : and, Chemical sensitivity of photoinduced Kʰβ hypersatelite transition in Cr compounds

Zeeshan, Faisal ; Dousse, Jean-Claude (Dir.)

Thèse de doctorat : Université de Fribourg, 2017 ; no. 2052.

The present PhD thesis includes three different projects which belong to the domain of inner-shell atomic physics and high energy resolution X-ray spectroscopy. The first project consists of a series of in-house measurements of the characteristic K and L X-ray absorption spectra (XAS) of several 3d, 4d and 5d transition metals. For this project the target chamber of the von Hamos curved crystal...
