Abstract

The structure of the cubic C-type phase of Gd2O3 has been refined using high-resolution powder neutron diffraction data. The sample was enriched in 160Gd to avoid the high neutron absorption of naturally occurring Gd. The refined structure is in excellent agreement with that estimated using perturbed angular correlation spectroscopy.
