"Since there is no theoretical basis for the quantization of electric charge, it is reasonable to consider the possible existence of particles with charges much less than the electronic charge ‘e’. Such particles, if they exist, are expected to ionize more lightly than the electron. Similar remarks hold true for particles with electric dipole moments, and relativistic monopoles with strengths much less than ’e’ electrostatic units. These particles have been termed subionizers.
The selection of apparatus for a subionizer search has been discussed. The desired conditions for such a search using a low background, long sensitive time Wilson cloud chamber have been outlined. The techniques by which the desired conditions are achieved are presented. A method of classifying the expansions as a function of (1) background and (2) chamber sensitivity, is established. The criteria for observing a subionizer track are outlined, and the techniques for a limited search were developed.
The apparatus has proved itself useful as a detection instrument for subionizers. Data obtained from a limited search is presented. No subionizers with z in the range 1/6 to 1/2 appeared in a body of photographs containing approximately 800 electron and meson tracks from cosmic rays and natural radioactivity"--Abstract.
