Abstract: The recent article by Cadle et al. (1975) describes a comparison of different types of condensation nucleus counters. Some general remarks are made here on the terminology and calibration of the counters and on the ...

Abstract: Experimental data on ice nucleation, presented in an earlier paper, are analyzed to yield information about the homogeneous nucleation rate of ice from supercooled liquid and the heights of energy barriers to that nucleation. ...

Abstract: The measurement of the temperature drop in a dry Pollak condensation nucleus counter by Israel and Nix has been interpreted as an indication that the expansion process does not yield as high a supersaturation as predicted ...

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 ...
