K. Jouda et al., X-RAY PHOTOEMISSION AND X-RAY-EMISSION SPECTRA IN RARE-EARTH TRIFLUORIDES, Journal of the Physical Society of Japan, 65(8), 1996, pp. 2585-2589
3d X-ray photoemission, valence band X-ray photoemission and 5p --> 3d
X-ray emission spectra of PrF3 and NdF3 are investigated. The charge
transfer energy, the effective hybridization and Coulomb interactions
are evaluated by the theoretical analysis of these spectra. It is show
n that al the experimental results are well reproduced by the theoreti
cal calculation with a set of parameter values for each compound. It i
s found that parameter values of the charge transfer energy and effect
ive hybridization systematically decrease in going from LaF3 to NdF3.
