TL;DR: In this paper, the two-strand rope and three-stranded rope models were described and used to illustrate the diffraction theory already developed, and it was shown that they would give a diffuse pattern.
Abstract: It is shown in this paper by Crick that when -helices of the same sense pack together they will probably do so about 20° away from parallel. For very long chains this may lead to a coiled-coil. The two simplest models - the two-strand rope and the three-strand rope - are described, and used to illustrate the diffraction theory already developed. It is shown that they would give a diffuse -pattern. Possible examples of these models are briefly discussed.
