Abstract

We have studied the elementary excitations of superfluid4He in a silica aerogel at 1.8 K and various filling fractions. The results do not show any departure from bulk4He behaviour, suggesting that previously observed anomalies in heat capacity and superfluid fraction data could be the effect of a distribution of He I and He II liquids inside pores of different sizes.
