采用Hartree-Fock方法计算了MgSe、CaSe和SrSe的能带结构，并进行了相关校正。我们的结果与这些岩盐结构绝缘体的光学数据进行了比较，预测了CaSe是直接间隙材料，而MgSe和SrSe都是间接间隙材料。
The electronic band structures of MgSe, CaSe, and SrSe have been calculated by the Hartree-Fock method with correlation corrections included. Our results are compared to optical data on these rocksalt-structure insulators predicting that CaSe is a direct-gap material while both MgSe and SrSe are indirect-gap materials.
