在γ-γ角关联实验中，发现能谱中全能峰的位置随探头方位角的改变而变化。本文通过不同的实验，验证了地磁对能谱测量的干扰以及对γ-γ方向角关联测量的影响。发现地磁对测量的影响主要来自光电倍增管，地磁方向与光电倍增管中电子飞行方向的夹角的改变，引起光电倍增管增益变化，最终给γ-γ方向角关联测量带来较大的影响。文中总结了如何减小地磁影响，改进γ-γ方向角关联实验测量的方法。

The position of the gamma characteristic peak changes along with the azimuth angle of the detector in the γ-γ angular correlation experiment. In this work,terrestrial magnetic field effects on the gamma energy spectrum measurement were studied as well as the influence to the γ-γ angle correlation measurement. This effect mainly comes from the photomultiplier tube. If the relative position between geomagnetic magnetic and photomultiplier changes,the gain of the photomultiplier will change owing to the impact of magnet on the flying electron in the photomultiplier tube. This change of the gain will affect theγ-γangular correlation experiment. Some suggestions were given to reduce geomagnetic magnetic effect and improve the γ-γ angle correlation measurement.
