Abstract:
Fifty-five interactions in the energy range 1 to 100 GeV of secondary particles of cosmic-ray jets have been examined. The energy was determined by finding the angle between the secondary and primary direction and assuming a transverse momentum of 0.4 GeVc. The interaction mean free path was 41.7 cm, the average number of shower particles varied from 1.3 to 6.4 and the average number of black prongs from 5.8 to 8.3 as the energy went from 2.8 to 34.6 GeV. The agreement with machine work is good, in contrast to previous experiments where the Castagnoli method of energy estimation andor area scanning was used. The application of the method to energies around 1000 GeV is discussed. Author
