Ionic fragmentation of methylmethacrylate has been observed using synchrotron radiation and laser excitation. A recently developed time-of-flight mass spectrometer was used for the ionic identification. In the case of ...

We present a detailed study of the ionization probability of H and H$_{2}^{+}$ induced by a short intense laser pulse. Starting from a Coulomb–Volkov description of the process we derive a multipole-like expansion where ...

We analyze the two-dimensional angular momentum-energy distribution of electrons emitted from argon by short laser pulses. We identify characteristic features of both multiphoton and tunneling ionization in the partial-wave ...

Above-threshold ionization of atoms by XUV short laser pulses is investigated close to the resonant 1s–2p transitions. Both ab initio TDSE and a theoretical Coulomb–Volkov like theory are used to study the enhancement in ...

Electron-momentum distributions for above-threshold ionization of argon in a few-cycle, linearly polarized laser pulse are investigated. Spectral features haracteristic of multiphoton as well as tunneling ionization coexist ...
