R. Glas et al., EXPERIMENTAL-OBSERVATION OF STATIC DISORDER IN C-60 BY DIFFUSE NEUTRON-SCATTERING, Physical review. B, Condensed matter, 50(2), 1994, pp. 692-697
A series of diffuse-neutron-scattering measurements on C60 powder mate
rial is presented. The results give evidence for the presence of signi
ficant static disorder below the 260-K ordering transition where besid
es the well-known simple cubic Bragg peaks elastic diffuse scattering
is observed. Additional measurements on a small C60 crystal likewise s
how elastic diffuse scattering below the ordering temperature.
