Abstract
The paramagnon model for the BCS-type state of superfluid 3He is applied to calculate the following properties in the ABM and BW states: the pressure dependence of the initial slope of the normalized superfluid mass density vs. 1 − T/T c; the pressure dependence of the normalized specific heat jump at T c; and the temperature dependence of the superfluid mass density at P = 20.7 and 27.6 bar. We also calculate the temperature dependence of the normalized nuclear spin susceptibility in the BW state. We compare our results with the experimental data on the A and B phases of superfluid 3He.
