   Abstract:
   Hydrogen absorption to give the dihydrides MH//2// plus //i containing interstitial hydrogen H//i has been studied for the metals Gd, Dy, Er, Yb and Lu in the form of films deposited in ultra-high vacuum on glass. Film areas were determined by Kr adsorption, and hydrogen content, in particular interstitial hydrogen H//i, characterized by gas uptake, temperature programmed desorption, electrical conductivity and work function measurements by the diode method.
