利用塞曼效应，在α-石英中观察到有效的正电子素[Ps=(e+e-)]四极相互作用。为了减少对样品的依赖，获得良好的分辨率，采用了湮没辐射的二维角相关技术。测得α石英晶体的四极耦合常数d为(3.0±0.9)×10-5 eV。
Effective positronium [Ps= (e + e - )] quadrupole interaction in α-quartz has been observed using the Zeeman effect on Ps. In order to reduce sample dependence and to achieve a good resolution, the two-dimensional angular correlation of annihilation radiation technique has been used. The quadrupole coupling constant d in α-quartz has been determined to be (3.0′0.9)×10 - 5 eV.
