Measurements on the cosmic radiation intensity in the mont blanc tunnel

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

Measurements on the muonic vertical intensity at different depths under rock (140; 290; 1325; 4100±100 m w.e.) have been performed in the M. Blanc tunnel. The experimental equipment is described. Our results are compared with the results obtained by other authors. Taking into account the valuesZ 2/A of the various types of rock there is a good agreement among all these measurements. The comparison of experimental points with the muonic spectrum at s.l. suggests to use the Weizsäcker-Williams instead of Kessler-Kessler virtual photonic spectrum in the calculation of the energy losses due to nuclear interactions.

Riassunto

Sono state eseguite delle misure sulla intensità muonica verticale a varie profondità sotto roccia nel tunnel del M. Bianco (e precisamente a 140, 290, 1325, 4100±100 metri di acqua equivalente). Viene descritto l’apparato sperimentale. I risultati vengono confrontati con quelli di altri autori. Tenendo conto dei valori diZ 2/A caratteristici delle varie rocce questi risultati sono in buon accordo. Il confronto con lo spettro muonico al l.d.m. suggerisce di utilizzare per il calcolo delle perdite di energia dovute ad interazione nucleare lo spettro fotonico virtuale di Weizsäcker-Williams in luogo di quello proposto da altri autori.
