摘要：

Investigations of quantum evaporation from the surface of superfluid He-4 at 20 mK have been carried out using both an electrical heater and a 5.5 MeV alpha source as generators of quasiparticles. The angular dependence of the evaporation signals for these two sources is found to be similar. The angular dependence and the total efficiency of the process are discussed in terms of models of quantum evaporation.
