Abstract
⺠Two rare earth metals, europium and terbium, have been compared in hydride formation. ⺠Hydrogen interaction with Eu or Tb films at 298 K leads to metal-semiconductor transition. ⺠Different resistance courses of Eu and Tb hydride films versus hydrogen content are noticeable. ⺠The inversion of polarization of the hydrogen adspecies is noted for both metals. ⺠Low temperature ordered surface phase of hydride for Tb (<100 K) and Eu (<160 K) is suggested.
