Dynamical relativistic effects in photoionization: spin-orbit-resolved angular distributions of xenon 4d photoelectrons near the Cooper minimum.
نویسندگان
چکیده
Two decades ago, it was predicted [Y. S. Kim et al., Phys. Rev. Lett. 46, 1326 (1981)] that relativistic effects should alter the dynamics of the photoionization process in the vicinity of Cooper minima. The present experimental and theoretical study of the angular distributions of Xe 4d(3/2) and 4d(5/2) photoelectrons demonstrates this effect for the first time. The results clearly imply that relativistic effects are likely to be important for intermediate- Z atoms at most energies.

Nondipole effects in the photoionization of xe 4d5/2 and 4d3/2: evidence for quadrupole satellites.
Measurements of nondipole parameters in spin-orbit-resolved Xe 4d photoionization demonstrate dynamical differences arising from relativistic effects. The experimental data do not agree with relativistic random-phase approximation calculations of single ionization dipole and quadrupole channels. It is suggested that the discrepancy is due to the omission of multiple-excitation quadrupole channe...
متن کاملStrong nondipole effects in low-energy photoionization of the 5s and 5p subshells of xenon
Large nondipole effects are predicted in the angular distribution of photoelectrons from the 5s and 5p subshells of xenon for photon energies below 200 eV. The nondipole parameter g5s exhibits a dispersion-curve variation near the first minimum of the 5s cross section at 35 eV, reaching a minimum value of 20.8 near 40 eV. Rapid variation of g5s is also found near the second minimum of the 5s cr...
متن کاملSpin-resolved off-normal photoemission from xenon adsorbates in comparison with free-atom photoionization
Energy-, angle, and spin-resolved photoemission studies on adsorbate systems were up to now restricted to the highly symmetrical set up of normal light incidence and normal photoelectron emission [I-3]. By use of the circularly polarized synchrotron radiation at BESSY in Berlin, the photoemission from the valence bands of rare gas adlayers on metal single crystals yielded a complete spin polari...
متن کاملElectron Correlations in Photoionization of Spin-Orbit Doublets
Measurements of absolute photoionization cross section of 3d subshell spin-orbit doublet components in Xenon 3d5/2 and 3d3/2 [1] are analyzed. Of particular interest is the observation of an additional broad maximum in the 3d5/2 cross section that lie 17.5 eV above the near threshold maximum. To understand the nature of this feature we have performed calculations of the cross sections and angul...
متن کاملSpin polarization of Auger- and of photoelectrons from barium atoms exposed to circularly polarized radiation and their cross comparison
New results of spin polarization of both photoelectrons and Auger electrons are reported after 5p photoionization of free Ba atoms with circularly polarized light. A substantial polarization transfer from the spin polarized photons to the spin polarized photoelectrons and via the hole state orientation to the spin polarized Auger-electrons is observed. The cross comparison of the results for ph...
