Time delay in molecular photoionization
Time-delays in the photoionization of molecules are investigated. As compared to atomic ionization, the time-delays expected from molecular ionization present a much richer phenomenon, with a strong spatial dependence due to the anisotropic nature of the molecular scattering potential. We investigate this from a scattering theory perspective, and make use of molecular photoionization calculatio...
متن کاملRelativistic effects in time delay of atomic photoionization
We study relativistic effects in time delay of atomic photoionization using an example of the Xe atom subjected to a circularly polarized electromagnetic pulse. We find that while relativistic effects play only a fairly small role for both the ionization probabilities and the time-delay of the co-rotating electron with the same sign of the angular momentum projection as the circularly polarized...
متن کاملTime delay in atomic photoionization with circularly polarized light
We study time delay in atomic photoionization by circularly polarized light. By considering the Li atom in an excited 2p state, we demonstrate a strong time delay asymmetry between the photoemission of the target electrons that are coand counter-rotating with the electromagnetic field in the polarization plane. In addition, we observe the time delay sensitivity to the polar angle of the photoel...
متن کاملTime delay in valence shell photoionization of noble gas atoms
We use the non-relativistic random phase approximation with exchange to perform calculations of valence shell photoionization of Ne, Ar, Kr and Xe from their respective thresholds to photon energy of 200 eV. The energy derivative of the complex phase of the photoionization matrix elements is converted to the photoelectron group delay that can be measured in attosecond streaking or twophoton tra...
متن کاملMolecular Frame Reconstruction Using Time-Domain Photoionization Interferometry.
Photoionization of molecular species is, essentially, a multipath interferometer with both experimentally controllable and intrinsic molecular characteristics. In this work, XUV photoionization of impulsively aligned molecular targets (N_{2}) is used to provide a time-domain route to "complete" photoionization experiments, in which the rotational wave packet controls the geometric part of the p...
