Abstract
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.
