Notes:
Neutron diffraction experiments have been completed on 243AmO2 and 244Cm2O3. The coherent-scattering amplitude of 243Am, relative to a value of 0.58 × 10-12 for oxygen, is 0.76 (1) × 10-12 cm. The value for curium is ̃0.7 × 10-12 cm, which cannot be determined accurately in this experiment because both C-type (cubic, a = 11.0 Å) and A-type (hexagonal, isostructural with La2O3) Cm2O3 are present in the sample. Some of the difficulties in performing neutron diffraction experiments on these radioactive isotopes, which exhibit self-heating and spontaneous fission, are discussed briefly.
