Summary

The results of the determination of the intensity and angular distribution of the Μ-mesons at a depth of 8.5-104 g/cm2 underground areI =I0 cosn θ withIo = (2.10±0.5) · 10−6 s−1 cm−2 sr−1 andn = 2.3 ± 0.3. The significance of the results in determining the parentage of theΜ-mesons is discussed.

Riassunto

I risultati della determinazione dell’intensità e della distribuzione angolare dei mesoni Μ alla profondità di 8.5·104g/cm2 sotto terra sonoI =I0 cosn θ conI =I0 cosn θ withIo = (2.10±0.5) · 10−6 s−1 cm−2 sr−1 en = 2.3 ± 0.3. Si discute il significato dei risultati in rapporto alla determinazione dell’origine dei mesoniΜ.
