Theoretical investigations of EPR g factors for Ce3+ ion at monoclinic Cs site in YAlO3 crystal

- The EPR principal g factors of monoclinic Ce3+ center in YAP crystal were explained.
- Two inconsistent EPR experiments for YAP:Ce3+ crystal were distinguished.
- The crystal-field strength parameters Sk were calculated and compared.
- The seeming abnormal negative power-law exponent t6 in SPM was actually reasonable.
