Abstract: A piston-typo expansion cloud chamber, capable of producing short pulses of nucleation, was used to study the homogeneous nucleation of water over a wide range of temperature and supersaturation. A large effort was made ...

Abstract: Observations of the homogeneous nucleation of water vapor in an expansion cloud chamber have been carried out for the temperature range ?50 to +17°C in the carrier gases argon and helium. We have found that the onset of ...
