Tunnel ionization of H_{2} in a low-frequency laser field: A wave-packet approach

Internuclear-distance dependence of electron correlation in nonsequential double ionization of H_2

“…3(c), which is consistent with previous theoretical results [11] and explained by the occurrence of an avoided crossing between the covalent ground state and the ionic excited state [12]. Figure 4(a) shows the R-dependent I p2 [22]. As R increasing, I p2 decreases monotonically.…”

“…For each internuclear distance R, the ground-state energy of H 2 is obtained from Ref. [22]. Similar to [18], b is set to 0.05.…”

Molecular Dissociative Ionization and Wave-Packet Dynamics Studied Using Two-Color XUV and IR Pump-Probe Spectroscopy

“…Among these approximations are a phenomenological description of the XUV ionization step [20], the neglect of rotational degrees of freedom [21] and also of the laser focal volume averaging [21].…”

Electron dynamics of molecular double ionization by elliptically polarized few-cycle laser pulses

“…For each R, the ground-state energy of the model molecules is obtained from Ref. [41]. To obtain the initial value for each R, the ensemble is populated starting from a classically allowed position for the corresponding ground state energy.…”
