Abstract

The proton spin-lattice relaxation times and Knight shifts have been measured in f.c.c. (δ-phase) and f.c.t. (ε-phase) ZrHx for 1.5 ≤ x ≤ 2.0. Both parameters indicate that N(EF) is very dependent upon hydrogen content with a maximum occurring at ZrH1.83. This behavior is ascribed to modifications in N(EF) through a fcc-fct distortion in ZrHx associated with a Jahn-Teller effect.
