Abstract
Measurements of the melting curve of He3 have been made between 16.6° mK and 0.7°K. The liquid and solid molar volumes at melting have been extended from 0.33°K to below 0.03°K, and the molar volume change on melting ΔVm obtained. An increase in ΔVm from 1.20 cm3/mole at 0.33°K to 1.28 cm3/mole at 0.06°K is found, with an extrapolation to 1.27 cm3/mole atT=0. Examination of the thermodynamic consistency of the data indicates that our melting curve slopes are accurate, within experimental error, down to a temperature of 0.04°K. The demagnetization apparatus is described, with considerable attention devoted to thermometry, thermal equilibrium, and experimental techniques. Construction details of the high-sensitivity capacitive strain gauge are given.
