Pulsed nuclear magnetic resonance in a tin single crystal

Abstract

Pulsed nuclear magnetic resonance studies of an isotopically pure 119Sn single crystal were made at 78 °K. An attempt to observe anisotropy in the spin–lattice relaxation time was inconclusive, but gave T1T = (34 ± 2) ms deg as the average value. Spin–spin relaxation was dominated by the pseudo-exchange interaction. The numerical value for this, (2.0 ± 0.5) kc/s, is in agreement with the value calculated from the Rudermann–Kittel theory. A strong pseudodipolar interaction was also observed.
