摘要
研究固体中的电子、声子、光子及磁振子等相互作用问题时,常常遇到确定其结构的空间群的选择定则。本文采用约化群的方法给出了 LaOF 结构 D3d5 空间群的选择定则,并对此进行了讨论,验证了其结果的正确性。
Frequently the selection rules for the space group of a structure should bewell determined when studying the interaction among eleectrons, photons andmagnetons of solids. Method of reducible groups is thus proposed to determinethe selection rules for the vspace groud D_3~5d of LaOF structure, with the app-licability and correctness of its results discussed and verified.
