Left column: Incident m=1 vortex with ring radius of 0.9 nm and displaced atoms (green disks: 0, 0.2, 0.6, 1, and 2 nm from the vortex center). Middle and right columns: Energy-filtered diffraction patterns of atomic chiral transitions with for incident waves with m=1 (middle) and m=−1 (right) in the Fe L edge. The values in the right bottom corners give the respective scaling factors for the intensities. The intensities in the lowermost panels are about 90 times weaker than those in the middle panels. The panels map scattering angles of ±10 mrad. (For interpretation of the references to color in this figure caption, the reader is referred to the web version of this article.)
