| Abstract: | A group of complete, strong-field-energy matrices for the perturbed Hamiltonian H' of the d5 ion system are constructed by using the Oh group representation strong field scheme. From this , we have successfully obtained a unified theoretical explanation of the spectrum and the cubic zero-field splitting of the ground state of Mn2+ ions in eight-ligand system (CaF2) and six-ligand system (KZnF3. RbCdF3) for the first time. The calculated values are in good agreement with the observed result. |
