| Abstract: | The density of states of4He clusters is calculated on the assumption that only surface vibrations are thermally excited. Results for mixed3He-4He and3He clusters are also given. The Weisskopf procedure is used to calculate the evaporation rates and the cooling laws of helium clusters at low temperatures. |
