Abstract
Conversely to previously reported data, EXAFS indicates that the As-O distances are similar in LiAsO3 and CaAs2O6. The main features of the XANES spectrum of LiAsO3, except the intense white line, come from sin gle and multiple scatterings on atoms found in a small cluster surroun ding the absorbing As atom (R < 3.6 Angstrom.
