“…in ionization potential and chemical interactions. The open shell nature of the Rg + [(m − 1)p 5 ] ion core leads, however, to specific properties of the rare gases such as series of prominent autoionization resonances between the two lowest ionization potentials 2 P 3/2 − 2 P 1/2 [1][2][3][4][5] and the presence of substantial admixture of d-valence character [6][7][8][9][10][11][12][13], which is especially strong for the Xe * (5p 5 6s J = 0) metastable level due to the proximity to the Xe * (5p 5 5dJ = 0) level [9][10][11][12][13]. The latter effects and the influence of electron correlations associated with virtual excitations of the core electrons [14][15][16][17][18][19] lead to the one photon excitation of nf Rydberg states besides np states and, On leave from: Rostov State University of Transport Communications, Rostov-on-Don, Russia correspondingly, cause the appearance of εf partial photoelectron waves besides εp waves in electric dipole single photoionization of Rg * , as described by the reactions:…”

Using high resolution laser photoelectron spectrometry we have determined absolute cross sections σ J0J1 and the electron angular distribution parameter for one photon ionization of metastable Xe * (6s 3 P J0 , J 0 = 2, 0) atoms to the resolved Xe + ( 2 P J1 , J 1 = 3/2, 1/2) ion states at several wavelengths near threshold. For comparison with the present and future experimental data we have calculated partial cross sections and β-parameters for photoionization of Xe * (6s 3 P J0 , J 0 = 2, 0) and of the analogous alkali atom Cs(6s) over the photoelectron energy range (0-5) eV. We have used both a term-dependent Pauli-Fock (PF) approach and a configuration interaction method involving Pauli-Fock atomic orbitals (CIPF). Through the PF method we include relativistic effects on the atomic orbitals; the CIPF method was designed to take into account the important electron correlation effects which are found to be essential for obtaining good agreement between the theoretical and experimental results.

“…Recent experimental work includes the crossed thermal beam-pulsed dye laser study of Rundel et al (dye laser width 4 cm-~) [13], the optogalvanic spectroscopy investigation of Grandin and Husson (cw dye laser width 2 cm-1 [15], the crossed fast Xe* beam -pulsed dye laser study of King and Latimer (laser width 0.6 cm -1) [17] and the crossed thermal Xe* beam -pulsed dye laser investigation of Knight and Wang (laser width 0.3 cm-1) [16] [17]. Knight and Wang [16] suggested that the fast beam results are influenced by unrecognized systematic errors.…”

“…Regarding the ionization with LIN, the PAD image [I LIN (y,z)] exhibits contributions with p-and f-type symmetries (see also Ref. [63,64]). A mirror axis can be chosen through the centre of the PAD image coinciding with the direction of the linear polarization (see Figure 3).…”

Photoelectron Circular Dichroism of Bicyclic Ketones from Multiphoton Ionization with Femtosecond Laser Pulses

Photoelectron circular dichroism (PECD) is a CD effect up to the ten-percent regime and shows contributions from higher-order Legendre polynomials when multiphoton ionization is compared to single-photon ionization. We give a full account of our experimental methodology for measuring the multiphoton PECD and derive quantitative measures that we apply on camphor, fenchone and norcamphor. Different modulations and amplitudes of the contributing Legendre polynomials are observed despite the similarity in chemical structure. In addition, we study PECD for elliptically polarized light employing tomographic reconstruction methods. Intensity studies reveal dissociative ionization as the origin of the observed PECD effect, whereas ionization of the intermediate resonance is dominating the signal. As a perspective, we suggest to make use of our tomographic data as an experimental basis for a complete photoionization experiment and give a prospect of PECD as an analytic tool.
