我们在UPt 3中进行了de Haas-van Alphen（dHvA）实验。在较宽的角度区域观察到一个新的分支。它的回旋有效质量为80 m0，磁场沿着[0001]方向的dHvA频率为5.66 × 107 Oe。新的分支很可能对应于5 f -巡游带模型第37带的主电子费米面。
We have performed the de Haas-van Alphen (dHvA) experiments in UPt 3 . A new branch has been observed in a relatively wide angle region. It has a large cyclotron effective mass of 80 m 0 and the dHvA frequency is 5.66 ×10 7 Oe for the field along the [0001] direction. The new branch most likely corresponds to the main electron Fermi surface in the 37th band of the 5 f -itinerant band model.
