旋转样品核四极共振的量子绝热微扰论分析

ANALYSIS OF THE NUCLEAR QUADRUPOLE RESONACEFOR A ROTATING SAMPLE IN TERMS OF THE QUANTUMADIABATIC-PERTUBATION THEORY

结合验证Berry几何相因子的Tycko旋转样品核四极共振实验,针对简并情况进一步发展并完善了作者之一最近提出的量子绝热微扰理论.应用这个理论,详细分析了任意自旋情况下具有核四极矩的旋转样品在射频场中的共振吸收,指出了可能的新的实验现象.

For the degenerate case, the quantum adiabatic pertubation theory proposed recently in Ref. [6] is further developed in connection with Tycko's experiment of nuclear quadrupole resonace testing the Berry's phase. Using this developed theory, we, analyse the resonace asorption of the radio frequency field by a rotating sample with a nuclear quadrupole in detail and point out the possible new phenomenon in the corresponding experiment.
