我们利用偏振相关的三维角分辨光电子能谱和角相关的偶极选择定则分析，报道了铁基超导体LiFeAs的费米面轨道特性。所评估的轨道特性通过能带计算得到了很好的重现。结果表明，偏振相关的角分辨光电子能谱与选择定则分析相结合，对于确定铁基非常规超导电性的轨道特性是有用的。
We report the orbital character of the Fermi surfaces for the Fe-based superconductor LiFeAs using the polarization-dependent three-dimensional angle-resolved photoemission spectroscopy and the angular-dependent dipole selection rule analysis. The evaluated orbital character is well reproduced by the band calculation. The results demonstrate that the polarization-dependent ARPES combined with the selection rule analysis is useful to identify the orbital character of the Fe-based unconventional superconductivity.
