Abstract
We have investigated the superfluid transition of He-3 in different samples of silica aerogel. By comparing new measurements on a 99.5% sample with pr evious observations on the behavior of He-3 in 98% porous aerogel, we have found evidence for a scaling of the transition temperature and superfluid d ensity of He-3 to the correlation length of the aerogel.
