The ab initio self-consistent DV-Xa (discrete variational Xa) method was used in its relativistic and spin-polarized model to investigate the ground-state electronic structttres of the crystal YPO4 and YPO4:RE^3+ ...
The structure of the low-temperature 4f^N→4f^N-15d excitation spectra of Eu^3+ and Tb^3+ doped in crystals LiYF4, YPO4 and CaF2 measured by van Pieterson et al. in 2002 was analyzed and assigned based on the simple...
