摘要
本文研究了半整数四极体系中心跃迁的自旋锁定,认为占据|-1/2>与|1/2>态的粒子可构成一个孤立的子体系,用密度算符理论证明了旋转坐标系自旋温度理论在这子体系中仍适用。在实验上用NaNO_2和NaOH粉末样品验证了上述结论。
Spin-locking o f central transition in half-integer quadrupolar systems was studied. The particles which occupy the states of |-1/2> and |l/2> may form an isolated sub-system, and it obeys the spin temperature theory in rotating frame. We calculated the intensity of spin-locking signal by density operator approach. The result was verified by experimental observations on 23Na-NMR spectra of NaNo2 and NaOH powders.
