CIRCULAR-DICHROISM IN RADIATIVE AND NONRADIATIVE INELASTIC XUV SCATTERING

Differences in cross-sections for left and right circularly polarized light are analyzed for radiative and nonradiative inelastic scattering by randomly oriented systems. It is shown that special experimental a rrangements result in finite dichroism. In radiative scattering the di chroism is related to the polarization state of the detected radiation . In the nonradiative case we show, using time-independent resonant sc attering theory, that dichroism also exists for a J = 1/2 intermediate virtual hole in contrast to results based on the assumption that the formation of the hole occurs separately from the decay.
