我们利用相对论密度泛函理论提出了一种具有自相互作用校正的方法，该方法简单、快速且具有合理的精度。与由低到高的几个原子的实测线及其超卫星的比较表明，相对论局域密度近似适用于线。相比之下，具有自相互作用校正的相对论性局域自旋密度近似更适合于超卫星。与非相对论密度泛函理论相比，我们发现即使对于中间原子，如Cu，相对论效应也是显著的（约100 eV）。讨论了从内壳到外壳的屏蔽效应和传导带。本文给出了介子原子的所有跃迁线，通过与测量值的比较，可以缩小可能跃迁的范围。
We develop a method using relativistic density-functional theory with a self-interaction correction, which is simple and fast yet has reasonable accuracy. A comparison with measuredlines and their hypersatellites of several atoms, from lowto high, reveals that the relativistic local density approximation is suitable forlines. In contrast, the relativistic local spin density approximation with a self-interaction correction is better forhypersatellites. Compared with the nonrelativistic density-functional theory, we found that the relativistic effect is significant (about 100 eV) even for middle-atoms, such as Cu. The screening effects, from inner shell to outer shell, and the conduction band, are also discussed. The present paper provides all the transition lines of muonic atoms, which can be used to narrow down the possible transitions by comparing them with the measurements.
