Spin-orbit coupling in tungsten by spin-polarized two-electron spectroscopy

Abstract: We present experimental results on low-energy spin-polarized two-electron spectroscopy of W(100) and W(110). A combination of a coincidence technique with the time-of-flight energy analysis was used to record angular and energy distributions of correlated electron pairs excited by spin-polarized low-energy primary electrons from a single crystal of tungsten. These distributions depend strongly on the polarization and the angle of incidence of the incident electron beam. Experimental data are discussed in terms… Show more

“…[1][2][3][4][5][6][7][8] Nowadays, a lot of experimental data are available for electron impact single ionization of simple and complex atomic and molecular targets. [9][10][11] However, many-body problems still remain unsolved. In this context, several theoretical models have been developed in last decades to describe the ionization processes at different projectile energies and various geometries.…”

“…The (e, 2e) processes, have become a powerful tool to investigate the dynamics of the ionization process. The (e, 2e) on hydrogen atom may now be considered to be a solved problem [1][2][3][4][5][6]. Following the single ionization, complex processes such as double ionization, simultaneous excitation ionization and auto ionization [7][8][9] have also been investigated.…”

“…Single ionization of helium with the ion being left in the ground state can also be treated as a 3-body problem however, in general, approximations have to be made. Development of a number of theoretical models to describe the ionization has been made that deal with different targets, impact energies and geometries [4][5][6][7][8][9][10][11][12][13]. Each model uses different approximations and as a result, the experiments play an important role in verifying the accuracy of theoretical approximations and guiding the calculations.…”
