DIRECT PRODUCTION OF ELECTRON PAIRS BY HIGH ENERGY ELECTRONS (in French)

Journal Article · · Helvetica Physica Acta (Switzerland)
OSTI ID:4285893
The methods of energy measurement of electron pairs were improved. The limits of application of direct angle measurements were recalculated, and the three dimensional model of track formation, which accounts for the variation of ionization on the initial track of electron pairs. was perfected. These results confirm the energy measurements made for the determination of the mean free path lambda of direct electron pairs production. It was found that the Kaplon and Koshiba factor f/sub i/ used for the calculation of the number of pseudotridents is too large. This can introduce an overestimation on lambda up to four times at 100 Gev. If the disagreement between Bhabha and Racah's theoretical values and the experimental determination of lambda seem to be established, the values deduced from Stueckelberg's remark agree quite well with the experiment. The influence of anomalous' trident production on shower development was also calculated. (auth)
