Energy levels in rare-earth ions
The tensor-operator and group-theoretical methods of Racah are used to examine the following contributions to the Hamiltonian of a rare-earth ion: ( a ) the Coulomb interaction ...

The terms and levels of the configuration ƒ 2 , corresponding to Pr 3+ , are examined. It is shown that it is essential to allow for the breakdown of Russell─Saunders coupling w...
The formulae of Redmond are used to construct expressions for the fractional parentage coefficients relating the configurations l 3 and l 2 . The explicit occurrence of godparen...
