从几个等温线上的压力和密度的测量中确定了~ 3 He气体在1.3和0.6K之间的第二维里系数。密度是从超导微波谐振腔的谐振频率是依赖于它的气体的介电常数。压力也确定使用谐振超导射频腔，在这种情况下，弯曲的隔膜是源的频率对压力的依赖性。实验技术在低压力和低密度下工作良好。维里系数表现良好，并在较高的温度下与他人的实验工作。
The second virial coefficient of 3He gas has been determined between 1.3 and 0.6 K from measurements of pressure and density on several isotherms. The density was derived from the resonance of a superconducting microwave cavity whose frequency was dependent on the dielectric constant of the gas within it. The pressure was also determined using a resonant superconducting rf cavity, in this case the flexing of a diaphragm being the source of the dependence of frequency on pressure. The experimental techniques work well at low pressure and densities. The virial coefficient appears well behaved and in agreement with the experimental work of others at higher temperatures.
