Abstract
In order to determine the oxygen coordination of the Bi3+ ion in LaPO4---Bi, extended X-ray absorption fine structure (EXAFS) spectra were measured of BiPO4 and LaPO4---Bi. Analysis of the EXAFS data shows that the Bi3+ ion in LaPO4---Bi occupies the La3+ site, but that the oxygen coordination of the Bi3+
