摘要
讨论了自旋为1/2的粒子在旋转磁场中的演化.利用旋转坐标系方法精确求出了其演化波函数,并用这个精确解计算了共振和非共振情形下的自旋翻转率、自旋极化矢量以及非绝热几何位相.
The evolution of spin 1/2 particles in a rotating magnetic field is discussed. Then the wavefunction of the spin 1/2 particles by using the method of rotating frame is also obtained. At last, the spin reversal ratio, spin polarization vector and non-adiabatic geometric phase in case of resonance and non-resonance are calculated.
