چکیده

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 calculations to examine this effect in representative homonuclear and hetronuclear diatomic molecules, nitrogen and carbon monoxide. We present energy and angleresolved maps of the Wigner delay time for single-photon valence ionization, and discuss the possibilities for experimental measurements.

Attosecond time delay spectroscopy of the hydrogen molecule

Attosecond science has extended experimental studies of atomic and molecular photoionization into a new dimension. In atoms, a time delay between absorption of an attosecond XUV pulse and subsequent emission of a photoelectron has been measured [1, 2, 3]. In molecules, electron localization and attosecond control have been demonstrated in pump-probe photoionization experiments [4, 5]. Experimen...

A MODEL STUDY OF LASER ISOTOPE SEPARATION BY PHOTOIONIZATION OR PHOTODISSOCIATION PROCESS

In this study, the selective photoexication of isotopic mixtures by laser light is investigated. Atomic and molecular methods are examined and rate equations are derived for both cases. Two and three step photoionization techniques are considered and rate equations are solved for ion yields. The molecular photodissociation process is also studied and the dependence of the dissociation produ...

Time 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...

Relativistic 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...

Time 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...
