Fig. 7

Simulation of the angular shift of small features in the DCS of a scattering process. a Schematic representation of the Newton diagram describing the scattering of two beams with particles of equal mass and equal pre-collision speed, with the relative velocity vector oriented horizontally. A DCS with a block feature as defined in panel (b) results in the gray area when the Newton sphere is crushed onto a two-dimensional plane. c Integration of the image intensity in an annulus between r min and r max results in an angular intensity distribution (shown by the red curve) that is shifted towards forward scattering with respect to the original DCS. This figure has been originally published in the supplement of reference [2] and was slightly adapted
