Photostar production between 500 and 1100 MeV

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

Experimental results are reported on the photoproduction of stars in photographic emulsions exposed to a high energy bremsstrahlung beam of maximum energies between 500 and 1100 MeV. The cross-sections, per number of equivalent quanta and per photon are calculated. The results are compared with those which can be derived using experimental values of the cross-sections for single and multiple pion photoproduction. Good agreement is found.

Riassunto

Si presentano i risultati ottenuti sulla fotoproduzione di stelle in emulsioni nucleari irraggiate con raggi γ di bremsstrahlung di energia massima compresa tra 500 e 1 100 MeV. Vengono calcolate le sezioni d’urto per quanto equivalente e per fotone. I risultati vengono confrontati con quelli di precedenti autori ad energie inferiori e con quelli deducibili dai valori noti per fotoproduzione singola o multipla di π, e si trova un buon accordo.
