报道了静水压力对铜、银和金费米表面的六个极值横截面影响的新高精度测量。使用了液氦、德哈斯-范阿尔芬相移技术，其结果具有足够的精度，可以对线性标度的偏差进行有效的傅立叶展开和相移拟合。等高线立体图表明，在所有情况下，费米表面球形度造成的现有扭曲都会增加。颈部横截面变化的结果与之前铜和金的数据一致，显示总变化率分别是缩放率的 4.2 和 5.6 倍，但发现银的颈部以缩放率约 10.6 倍增加，与之前的 7.3 倍数字不一致。
New high precision measurements of the effect of hydrostatic pressure on six extremal cross sections of the Fermi surfaces of copper, silver, and gold are reported. The fluid-helium, de Haas – van Alphen phase-shift technique was used, and the results were of sufficient precision that valid Fourier expansion and phase-shift fits to the departures from linear scaling could be made. Contour stereograms show that in all cases the existing distortions from sphericity of the Fermi surface are increased. The results for changes of neck cross section are in agreement with previous figures for copper and gold, showing total rates of change 4.2 and 5.6 times scaling respectively, but the neck in silver is found to increase at about 10.6 times the scaling rate, in disagreement with an earlier figure of 7.3 times.
