    Notes: Abstract High-precision measurements of the3He melting pressure versus temperature have been made from 500 μK to 25 mK using a60Co nuclear orientation primary thermometer and a Pt NMR susceptibility secondary thermometer. Temperatures for the fixed points on the melting curve are: the superfluid A transition TA = 2.505 mK, the A-B transition TAB = 1.948 mK, and the solid ordering temperature tn = 0.934 mK. These fixed points and a functional form for P(T) constitute a convenient temperature scale, based on a primary thermometer, usable to well below 1 mK.

    Notes: Abstract Direct nuclear demagnetization is used to cool high density solid3He into the magnetically ordered phases. The pressure change in the samples is detected by a capacitive strain gauge. The entropy of the samples is removed by precooling to a temperature of 0.5 mK in a field of 2.5 T. For a bcc sample with a molar volume of 20.10 cm3/mol, two magnetic transitions have been observed. A similar experiment on an hcp sample with a molar volume of 19.65 cm3/mol is being done. Preliminary data indicates no abrupt change in the pressure as observed in the bcc sample.
