the fitting program gave out the fitted crystal field parameters. When the fitting results came out
each energy level was assigned the irreducible representation.The symmetry on CS

the parameters of calculated and fitted were compared. Tile calCulated and experiment spectra were compared also.The enviroment around the rare earth ions Eu

the fitting results reveal this by comparing the correspondent parameters and the standard deviation of the fitting under different assumed symmetry.
