摘要：

This work is motivated by recent experiments studying superfluid He-3 inside porous aerogel. Using the homogeneous scattering model, we calculate the pairing amplitude and the superfluid density for the A and B phases at all temperatures. At high temperatures the results are in agreement with simpler calculations based on the Ginzburg-landau theory. We also study the effect of large impurities in the B phase. We find that higher scattering channels give essentially the same results as obtained by limiting to s-wave scattering. (C) 1998 Elsevier Science B.V. All rights reserved.
