We present a comprehensive analysis of autoionization processes in Ne clusters (~5000 atoms) after multiple valence excitations by free electron laser radiation. The evolution from 2-body interatomic Coulombic decay (ICD) to 3-body ICD is demonstrated when changing from surface to bulk Frenkel exciton excitation. Super Coster-Kronig type 2-body ICD is observed at Wannier exciton which quenches the main ICD channel.
Attosecond time delays in C60 valence photoemissions at the giant plasmon
2015, Barillot, T., Magrakvelidze, M., Loriot, V., Bordas, C., Hervieux, P.-A., Gisselbrecht, M., Johnsson, P., Laksman, J., Mansson, E.P., Sorensen, S., Canton, S.E., Dahlström, J.M., Dixit, G., Madjet, M.E., Lépine, F., Chakraborty, H.S.
We perform time-dependent local density functional calculations of the time delay in C60 HOMO and HOMO-1 photoionization at giant plasmon energies. A semiclassical model is used to develop further insights.
