Spin polarization of Auger- and of photoelectrons from barium atoms exposed to circularly polarized radiation and their cross comparison
Kuntze R, Salzmann M, Böwering N, Heinzmann U. Spin polarization of Auger- and of photoelectrons from barium atoms exposed to circularly polarized radiation and their cross comparison. Zeitschrift fĂŒr Physik D: Atoms, Molecules and Clusters. 1994;30(2-3):235-237.New results of spin polarization of both photoelectrons and Auger electrons are reported after 5[Rho] 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 photoelectrons and Auger-electrons allows a quantitative test of the assumed two step model where both electron-emission processes occur in sequence
Perceived managerial and leadership effectiveness in UAE and Egypt: a comparison through the combined lenses of Islamic work ethics and Islamic leadership
Despite the increasing awareness that societal, sectorial, and organizational variables have a significant impact on manager and employee behavior, most studies in Asian and Middle Eastern (ME) countries, whether conducted by Western or indigenous scholars, continue to be informed by frameworks derived from the United States (US), Canada, or Western European countries (Leung, 2007; Li, 2012; Tsui, 2006) . This approach is problematic because the insights gleaned from such studies may fall only within Western theoretical constructs (Tsui, 2007; see also Shahin & Wright, 2004), thereby compromising insights regarding novel country-specific phenomena and the development of indigenous management/leadership knowledge. Consequently, many scholars (Rosenzweig, 1994; Rousseau & Fried, 2001) have called for the generation of indigenous management theories based on local conditions and socio-cultural factors, and for indigenous management and leadership research within non-Western countries (see Holtbrugge, 2013; Wolfgramm, Spiller & Voyageur, 2014; Shahin & Wright, 2004). This call is also pertinent for ME countries, where there is generally a paucity of indigenous management/leadership research and more specifically, of inductive emic (context-specific
Performance results of laser-produced plasma test and prototype light sources for EUV lithography
Spin-resolved Auger electron spectroscopy of barium atoms
Kuntze R, Salzmann M, Böwering N, Heinzmann U. Spin-resolved Auger electron spectroscopy of barium atoms. Physical review letters. 1993;70(24):3716-3719.The angular dependence of the spin polarization of Auger electrons was measured after 5p photoionization of free Ba atoms with circularly polarized light. A substantial polarization transfer from the oriented photoion onto the Auger electrons was observed in confirmation of theoretical predictions by Kabachnik and Lee. The ratio of the dipole transition matrix elements and the orientation and alignment coefficients were extracted from the experimental data for the Auger electron polarization parameters

Evidence for a molecule rotation-dependent spin-polarization transfer mechanism in the photon-induced autoionization of HCl and DCl
Drescher M, Irrgang R, Elizarov A, Böwering N, Heinzmann U. Evidence for a molecule rotation-dependent spin-polarization transfer mechanism in the photon-induced autoionization of HCl and DCl. PHYSICAL REVIEW LETTERS. 1995;75(16):2936-2939.High resolution spectra of the angle-integrated photoelectron spin polarization, after excitation of HCl and DCl with circularly polarized laser radiation, reveal pronounced rotational autoionization structures. The data, interpreted in terms of Rydberg series converging to limits with different ionic angular momenta of the (2) Pi(1/2) fine structure component, clearly indicate a systematic dependence of the sign of the spin polarization on the rotation of the molecular ion core. Application of the current theoretical model leads to consequences for the angular momentum transfer in the autoionization process
