We report the first experiments in which 5-MeV alpha particles are detected via evaporation from a bath of superfluid helium. The {alpha} excites phonons and rotons in the liquid helium, and these excitations are sufficiently energetic to evaporate h

At a critical negative pressure {ital P}{sub {ital e}}, liquid {sup 3}He and {sup 4}He become macroscopically unstable. We give a theory of the critical behavior near {ital P}{sub {ital c}} and show that it is in excellent agreement with the experime

This is a short review of recent experimental and theoretical studies of phonon interactions in superfluid helium. Phonon--phonon scattering in helium is strongly influenced by the conservation laws and by the peculiarities of the phonon dispersion r

A new method for detecting solar neutrinos and other weakly interacting particles is proposed and described. The detector consists of a large mass of superfluid helium at low temperatures (20 mK). When a neutrino is scattered off an electron, the rec
