Figure 8
Left: kinetic energy shift measured as a function of the delay between the 50 fs laser excitation and the synchronized isolated synchrotron pulse in the α/25 SOLEIL filling mode. Right: kinetic energy shift measured during the decay process using the consecutive filling part of the synchrotron radiation time structure. The inset shows the Si-2p spectra measured before (black line) and 100 ps after (red curve) the laser excitation. Experiments were performed with 150 eV photon energy. |
