IONIZATION MEASUREMENTS IN H$sub 2$ ON POSITRONS AND NEGATRONS OF 250 Kev WITH A CLOUD CHAMBER (in German)
S>With a hydrogen-filled cloud chamber, a comparison or the ionization of positrons and negatrons in the energy range between 258 and 207 kev was made with the same conditions for both Particles (average energy and energy distribution of the particle groups and supersaturation in the chamber). The measurements showed no variation between the two particles either for the primary ionization or for the practical ionization (average ionization). The value of the primary ionization corrected to hydrogen in normal conditions was in good agreement with the results of previous workers. By an extension of the Kunze method, a formula was derived for the correction of the common overlapping of drop formations. For a comparison of the measured practical ionization with the theoretical results, it is necessary to know the number of "drop clusters" simulated by statistical fluctuations of the ionization. A method was drafted for the estimation of this number. The method was applied to various cases. (tr- auth)
