WitrynaInterstitial defects are atoms that occupy a site in the crystal structure at which there is usually not an atom. They are generally high energy configurations. Small atoms (mostly impurities) in some crystals can occupy interstices without high energy, such as hydrogen in palladium. http://users.ictp.it/~markusm/Papers/ClassicalImp_in_QChains.pdf
