Structural studies of a carbonate fluorapatite from powder neutron diffraction data

摘要

Neutron powder diffraction data from 295K to 10 K of a natural carbonate fluorapatite (francolite) were refined to examine static versus dyanmic disorder as revealed by the temperature dependence of the atomic displacement parameters (ADP). The refined P-O1 and P-O2 bond lengths are correspondingly approx 4
