我们报告了注入多晶氢化锂 (LiH) 的 57Mn 的束内穆斯堡尔谱。将束内穆斯堡尔谱数据与密度泛函理论（DFT）计算结果进行比较，发现57Fe原子被植入LiH晶体中的Li或H取代位点。通过将样品温度从 11 K 更改为超过 800 K，我们观察到在具有相邻 Li 或 H 原子缺陷的替代 H 位点处 57 Fe 还原，并且在没有相邻原子缺陷的替代 H 或 Li 位点处添加 57 Fe。它表明退火效应诱导的恢复。
We report the in-beam Mössbauer spectra of57Mn implanted into polycrystalline lithium hydride (LiH). Comparing the in-beam Mössbauer spectra data with the results of density functional theory (DFT) calculations,57Fe atoms were implanted into Li or H substitutional sites in the LiH crystal. By changing the sample temperature from 11 K to over 800 K, we observed a reduction of57Fe at a substitutional H site with a neighboring Li or H atom defect, and an addition of57Fe at substitutional H or Li site without neighboring atom defects. It suggests annealing effect-induced recovery.
