Abstract

The g values of the 5f⁵ ions Pu³⁺ and Am⁴⁺ in CeO₂ cubic symmetry sites have been measured by EPR techniques and found to be 1.333 ± 0.001 and 1.3120 ± 0.0005, respectively. For the case of Pu³⁺, the cubic crystal field parameters were calculated and compared with those previously obtained for other fluorite‐structure lattices. The EPR spectrum was also observed for ²⁴¹Pu in ThO₂ and the ratio of the magnetic moments ²⁴¹μ_I/²³⁹μ_I determined to be 3.52 ± 0.06.
