四面体结构的固态等价轨道和能态的自旋--轨道耦合双群分类

本文按照Ｃ—Ｃ单键和烃类化学键的性质，根据ＬＣＡＯ—ＭＯ近似法，将原子波函数基转变为四面体分子的酉等价轨道基，并由这一套酉等价基组合出金刚石、ＧａＡｓ这类等电子晶体离域化的基Ｂｌｏｃｈ函数。详细分析了晶体能带结构中简并态的对称性约化分解。给出了自旋一轨道耦合的主要应用．

SOLID STATE EQUIVALENT ORBIT WITH TETRAHEDRAL STRUCTURE AND DOUBIE GROUP CLASSIFICATION OF SPIN-ORBIT COUPLING FOR ENERGY STATES

The basis of atomic wave function, as suggested here is to be transformed into the unitary equivalent orbital basis of the tetrahedral molecule, which is based on LCAO-MO approximate method in the quantum chemistry according to the nature of the C-C single bond and the chemical bond in hydrocarbons. Again, by using the unitary equivalent basis, a basis Bloch function of the isoelectronicity crystal delocalization for diamond, GaAs and the like is for- med, The symmetry reduced to decomposition of the degenerate states in stru- cture of energy band for crystals had been analysed in detail The essential applications of the spin-orbit coupling are presented.
