Past experiments about hydrogen absorption in niobium have revealed specificproperties about interactions between interstitial hydrogen atoms. It has beenreported that there are long-range attractive and short-range repulsiveinteractions between interstitial hydrogen atoms in niobium. It has also beenreported that these interactions are of many-body nature. While previousunderstanding of these interactions is based on experimental inferences frompast experiments, through these calculations, for the first time, we canunderstand the nature of the interactions at a fundamental level. In this work,we use Density Functional Theory calculations to study the interactions ofinterstitial hydrogen atoms in niobium. We report here that these interactionsare a combination of an attractive, indirect image interaction and a repulsive,direct interaction. Through our calculations, we also infer here that theseinteractions indeed have many-body characteristics.
