Abstract
An ionization gauge of the type described by Found and Dushman was calibrated for helium, neon, nitrogen, argon and mercury. The results obtained have been compared with those derived by means of a graphical integration based on the probability of ionization of different gases as a function of electron velocity. The agreement is very satisfactory. The present results indicate that the purely empirical relation between sensitivity and ``molecular number'' (total number of electrons per molecule), reported in the earlier paper, is not generally valid.Keywords
