Photoelectron angular distribution in bichromatic atomic ionization

Photoelectron angular distributions for atomic chlorine.

The photoelectron angular distribution of water clusters.

The angular distribution of photoelectrons emitted from water clusters has been measured by linearly polarized synchrotron radiation of 40 and 60 eV photon energy. Results are given for the three outermost valence orbitals. The emission patterns are found more isotropic than for isolated molecules. While a simple scattering model is able to explain most of the deviation from molecular behavior,...

Bichromatic atomic lens.

We investigate the focusing of three-level atoms with a bichromatic standing wave laser field, using both classical and quantum treatments of the problem. We find that, for the appropriate ratio of detunings to Rabi frequencies, the atoms will experience a periodic potential which is close to harmonic across half an optical wavelength. The field thus becomes equivalent to a periodic array of mi...

Photoelectron angular distribution and molecular structure in multiply charged anions.

Photoelectrons emitted from multiply charged anions (MCAs) carry information of the intramolecular Coulomb repulsion (ICR), which is dependent on molecular structures. Using photoelectron imaging, we observed the effects of ICR on photoelectron angular distributions (PAD) of the three isomers of benzene dicarboxylate dianions C6H4(CO2)2(2-) (o-, m- and p-BDC(2-)). Photoelectrons were observed t...

Valence electron ionization dynamics of chromium by a photoelectron imaging technique: J+-dependent state and angular distribution.

The photoionization of Cr at excited states is investigated using a velocity-map photoelectron imaging technique. Benzene chromium carbonyl or bis(η(6)-benzene) chromium was used as a precursor for the generation of excited Cr atoms. The a (5)S2 → x (5)P°3 and a (5)D3 → y (5)D°2 transitions are then employed for the preparation of resonant intermediate states in a two-color two-photon ionizatio...
