Abstract
The internal friction of α-LuH(D)x, with 0 ≤ x ≤ 0.2, has been measured in the range 4.2 ≤ T ≤ 450 K both in the annealed state and after deformation. Three main peaks were observed and designated according to their characteristics : (1) "H"-peak - at 215-225K, with an x-dependent amplitude and an isotope-dependent temperature ; (2) "d-H"-peak - at 250-260 K, appears after deformation in the H(D)-containing samples only ; (3) "d"-peak
