Elliptic and circular dichroism effects in two-photon double ionization of atoms.

Polarization control of direct (non-sequential) two-photon double ionization of He

An ab initio parametrization of the doubly-differential cross section (DDCS) for twophoton double ionization (TPDI) from an s2 subshell of an atom in a S0-state is presented. Analysis of the elliptic dichroism (ED) effect in the DDCS for TPDI of He and its comparison with the same effect in the concurrent process of sequential double ionization shows their qualitative and quantitative differenc...

Circular dichroism e ects in atomic x

It is shown that a speciic beyond-dipole-approximation polarization eeect in elastic photon-atom scattering, resulting in circular dichroism (CD) when the scattered photon has a suitable observed linear polarization, has signiicance in the x-ray regime. Ground state atoms are considered, assumed to be randomly oriented. The cross section, given our assumptions, is written in terms of photon Sto...

Mass-selective discrimination of chiral molecules by femtosecond multi-photon photoelectron circular dichroism

In this chapter, the study of the chiral molecule Camphor is reported using femtosecond multi-photon ionization in combination with masscorrelated photoelectron coincidence imaging. It is shown that a relatively simple table-top experimental set-up can be used to detect massselected enantiomers with high selectivity and sensitivity. The novel technique that is coined multi-photon photoelectron ...

Perturbative analysis of the triply differential cross section and circular dichroism in photo-double-ionization of He

Probing of chirality inMethyloxirane by mass-selective femtosecond multi-photon photoelectron circular dichroism

In this chapter, the chiral molecule Methyloxirane is studied using femtosecond multi-photon ionization at 400 nm in combination with masscorrelated photoelectron coincidence imaging. The ion time-of-flight spectrum and the mass-correlated photoelectron kinetic energy distribution are discussed. The appearance energy of the parent ion and the fragment ion C2H + 4 in multi-photon excitation is r...
