Abstract
The fraction of molecules that vaporize from a surface and escape through a cylindrical hole to a condenser (escape probability) has been calculated by Monte Carlo methods for the case of hemispherical (concave and convex) and flat surfaces. The results for vaporization from the flat surface are in agreement with results predicted by the Clausing factor. The effect of condensation coefficients has also been investigated. A semiempirical equation of adjustable parameters was developed which represents the escape probabilities as a function of the length‐to‐radius ratio and the condensation coefficient .
