Abstract
We have observed sharp cusplike heat-capacity singularities, coincident with the superfluid transition, in two aerogel glasses. These features are interpreted as conclusive evidence of genuine critical behavior at the superfluid transition in these systems. The cusplike heat-capacity singularities confirm that aerogels are not in the same universality class as bulk helium.
