Description
The /sup 45/Sc nuclear spin-lattice relaxation time T1 in scandium dihydride and dideuteride measured up to 1300 K shows a second high-temperature minimum at --1100 K, in addition to the usual (Bloemberger-Purcell-Pound) minimum associated with independent motion of hydrogen vacancies among tetrahedral interstitial sites. This indicates the onset of a second mode of hydrogen motion with a relatively long associated correlation time for the hydrogen-scandium interaction. Possible origins for such long times are discussed
