Figure 16
PECs of the argon dimer between 10 and 45 eV. The potential energy E is given with respect to the Ar–Ar ground state. For simplification, only a single PEC is plotted to represent Ar+(3p−2nl)–Ar (dark-green) and Ar+(3p−1)–Ar+(3p−1) (blue) states. All curves are taken from Stoychev et al. (2008) and Miteva et al. (2014). [Reprinted with the permission of AIP Publishing.] The purple vertical arrows indicate photons of ℏω = 24.8 eV. The dashed arrow visualizes the absorption of a second photon in the pump pulse. The Franck–Condon (FC) region lies within the two vertical dashed gray lines. The figure is taken from Schmid (2018). |
