摘要: Abstract We report O 17 NMR measurements in a single crystal of NpO 2 . have observed oscillatory spin–echo decay for certain sites below T 0 = 26 K These oscillations are well understood terms an axially symmetric electric field gradient created by longitudinal triple-q antiferro-quadrupolar ordering. In the present work, we show that direct observation quadrupolar order parameters is possible means NMR.
