32个点群的晶场势及其与坐标系的关系

The crystal-field potentials of 32 point-group and its relationships with coordinate-system

基于晶体场理论,系统地给出了铁族离子32个点群的晶场势,并研究了坐标系取法不同时晶场势的变化.研究结果表明:对铁族离子,32个点群有8种不同形式的晶场势能.绕z轴转动坐标系时,晶场势相因子可变化.在立方晶系中,当z轴取向改变时,晶场势中出现新的项取代原来的项.

Base on the crystal-field theory, all of the crystal-field potentials of 32point-group are given for family iron ions and the relationships of which with different coordinate-system are studied. The results of the study indicate that there are 8 kinds of the crystal-field potentials for family iron ions and that the phasor of express of crystal-field potential are changed by rotating x-y plate of coordinate-system.
