Phys. Rev. A 8, 3093–3095 (1973)Search for a Discontinuity in the Density of Liquid He3 below 3 mKReceived 18 July 1973; published in the issue dated December 1973 The density of liquid He3 along the melting curve below 3 mK and through the transitions to the A and B phases has been studied using a parallel-plate capacitor in a Pomeranchuk cell. It is found that the density varies smoothly in this region with no discontinuity larger than Δρ/ρ=5×10-5. The existence of a latent heat demonstrates that the B transition is first order; however, the jump in density must be minute. © 1973 The American Physical Society URL:
