A UNITARY GROUP TREATMENT FOR STRONG CRYSTAL FIELD IN OCTAHEDRAL SYMMETRY

By utilizing the commutation properties of second quantized operators, a chain of groups has been obtained. This chain can serve the purpose of classifying state of d-electrons in octahedral symmetry. The symmetry wave functions, which are adapted to the chain of groups and expressed in the form of linear combinations of Gelfand state, are constructed. Moreover, The methods of calculating matrix elements are discussed systematically in this paper.
