Figure 2
Line series in real space (green and purple, right panel) generated by two nodes a and b in the 2D reciprocal space (left). The distances between adjacent parallel lines are given by the familiar reciprocal of the distance of magnitude of the momentum transfer of the node. A third node (a + b + noise, red) is shown, along with a corresponding set of lines in the right panel, to show that in the presence of noise there usually are no points where all sets of lines intersect. |
