Phase measurement of a Fano window resonance using tunable attosecond pulses
M. Kotur, D. Guenot, A. Jimenez-Galan +16
We study the photoionization of argon atoms close to the 3s3p 3s3p4p 3s3p , =s,d Fano window resonan…
Resonance effects in photoemission time delays
M. Sabbar, S. Heuser, R. Boge +6
We present measurements of single-photon ionization time delays between valence electrons of argon and neon using a coincidence detection technique that allows for the simultaneous…
Theoretical study of the isotope effects on the detachment thresholds of Si
T. Carette, M. Godefroid
The isotope effects in Si bound levels are studied using the multi-configuration Hartree-Fock ab initio approach. Large scale calculations are carried out for the $3p^3\ ^4S^o,…
The Multi-Configurational Hartree-Fock close-coupling ansatz: application to Argon photoionization cross section and delays
T. Carette, J. M. Dahlström, L. Argenti +1
We present a robust, ab initio method for addressing atom-light interactions and apply it to photoionization of argon. We use a close-coupling ansatz constructed on a multi-configu…
Diagrammatic approach to attosecond delays in photoionization
J. M. Dahlström, T. Carette, E. Lindroth
We study laser-assisted photoionization by attosecond pulses using a time-independent formalism based on diagrammatic many-body perturbation theory. Our aim is to provide an ab ini…
A theoretical study of the C- 4So_3/2 and 2Do_{3/2,5/2} bound states and C ground configuration: fine and hyperfine structures, isotope shifts and transition probabilities
T. Carette, M. R. Godefroid
This work is an ab initio study of the 2p3 4So_3/2, and 2Do_{3/2,5/2} states of C- and 2p2 3P_{0,1,2}, 1D_2, and 1S_0 states of neutral carbon. We use the multi-configuration Hartr…
