Electronic structure of U4+, Np4+, and Pu4+ doped into ThSiO4 single crystal

The optical spectra of tetravalent ions of early actinides, U4+, Np4+, and Pu4+, were interpreted via a semiempirical Hamiltonian in D2d site symmetry, in terms of electronic transitions within their respective 5fn ground state configurations. Systematic trends in the semiempirical parameters descri...

Description
Summary:The optical spectra of tetravalent ions of early actinides, U4+, Np4+, and Pu4+, were interpreted via a semiempirical Hamiltonian in D2d site symmetry, in terms of electronic transitions within their respective 5fn ground state configurations. Systematic trends in the semiempirical parameters describing the intraconfiguration transitions have suggested that those for U4+ ion are not representative of the light actinide series.
