Description
We report the in-beam Moessbauer spectra of 57Mn implanted into polycrystalline lithium hydride (LiH). Comparing the in-beam Moessbauer 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 of 57Fe at a substitutional H site with a neighboring Li or H atom defect, and an addition of 57Fe at substitutional H or Li site without neighboring atom defects. It suggests annealing effect-induced recovery. (author)
