摘要：

For low Hydrogen concentration it is assumed that protonic Hydrogen interacts in YBa2Cu3O7-y with other positive and negative ions through screened Coulomb interactions. The stable configuration of Hydrogen is not on symmetrical interstitial sites but more likely on a closed surface in coordinate space between positive and negative charged ions. The migration energy of Hydrogen in Y subcells is also calculated and found in good agreement with experimental findings; its value depends also on an anisotropy factor.
