Polarization of theLα1X Rays of Mercury

Polarization of TargetKX-Rays

“…pletely neglected, is the polarization of the first single-^-, multiple-L-shell-vacancy satellite. This satellite is due to the decay of the (ls)' 1 (2p)' 1 double-vacancy configuration 9 which couples to two terms 1 P l and 3 P 2fli0 ' These terms decay via three multiplets to the (2p)~2 final vacancy configuration and are labeled as follows: Ka' 0^-^SQ), ^«3( 3^2 ,I,O-3^2 .I,O), andtfa 4 CP^zg. An ideal system for the study of the polarization of these multiplets is a He beam on an Al target where the intensity of the first satellite is of the same order of magnitude as the intensity of the Ka lt2 line.…”

Coincidence Studies of Inner-Shell Excitation in Ion-Atom Collisions

“…As a result, x-rays emitted in transitions from different upper levels into the Ls subshell could not be distinguished; the integral polarization (a few percent) was rather difficult to extract from data. Hrdy et al (35) measured the polarization of La 1 x-rays from electron-impact ionization of Hg employing Bragg reflection from a quartz crystal. This necessitated a somewhat complicated analysis of the experimental data; the resulting polarization of about 14% appears considerably too high if compared to corresponding theories.…”

“…This is a less ambiguous situation than encountered in previous experiments. (28,35) Scholer and Bell(28) used a proportional counter to detect the proton-induced integral LI, La1,2 x-rays from Cu and Ge. As a result, x-rays emitted in transitions from different upper levels into the Ls subshell could not be distinguished; the integral polarization (a few percent) was rather difficult to extract from data.…”

Kinematic coefficient ratios, anisotropy parameters, and polarization degrees of L3 X-ray transitions of Bi, Pb, Ta, Lu, and Yb

“…From this alignment follows; the X-radiation should have a non-isotropic angular distribution and should be polarized [28]. Recent experiments demonstrated that the L, L␣, and L␤ X-rays are polarized [29][30][31][32][33][34]. Also, Scofield [35] gave the relativistic formulation for the angular distribution of the electrons produced in the photoionization by linearly polarized photons and the distribution of photons of a particular polarization produced in the inverse process of radiative recombination in the energy range below 100 keV for helium-like nickel and neon-like barium.…”
