Abstract: Results for the three Stokes parameters (polarization components) P 1, P2 and P3 of the VUV Hg transition 6s6p 1P1 → 6s2 1S0 (185 nm) obtained from electron-photon (e, eγ) coincidence measurements at electron impact energies of 15 eV, 50 eV and 100 eV (Aussendorf et al 2006 J. Phys. B: At. Mol. Opt. Phys. 39 2403) were combined to obtain the total degree of polarization . In addition, the Stokes parameter P4 was measured at an electron impact energy of 15 eV. The measured data are compared with predictions from a fullrelativistic distorted-wave calculation, a five-state semirelativistic Breit-Pauli R-matrix (close-coupling) model, and a convergent close-coupling ansatz, where relativistic effects are accounted for by recoupling of nonrelativistic results. In agreement with the theoretical predictions, no influence of the electron spin was observed for scattering angles ≤ 30°. At 15 eV excitation energy and scattering angles ≥ 40°, however, an increasing importance of spin effects is predicted. © 2006 IOP Publishing Ltd.
