Some arguments in support of the existence of a large fraction of planar boroxol rings (i.e. up to 80% of boron atoms participating in such structures) are given by A.C. Hannon, D.I. Grimley, R.A. Hulme, A.C. Wright and R.N. Sinclair, J. Non-Cryst. Solids 177, 299 (1994), whereas reconstructions of the experimental S(Q) diffraction pattern by means of reverse Monte Carlo techniques, seem to point to a rather low portion of these structures. J. Swenson and L. Björjesson (private communication).

According to the predictions of the "soft-potential model," a quasielastic broadening due to "soft modes" should exist, although such broadening only becomes evident at temperatures somewhat above ≈0.(Formula presented). For some detailed predictions of the soft-potential model, see, V.L. Gurevich, D.A. Parshin, J. Pelous and H.R. Schober, Phys. Rev. B 48, 16t318 (1993) and references to previous works.
