Production of fragments of mass number 6≦A≦11 in12C,14N and16O spallation by alpha-particles at energies near threshold

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

The yield of fragments of astrophysical interest 6≤A≤11 emitted in complex interactions of α-particles with the C, N, O nuclei of the nuclear emulsion has been experimentally determined at energies near the threshold of production. Reaction products have been identified through a kinematical analysis of each interaction. Production cross-sections have been computed and the contribution of the different reaction channels to each isotope elucidated.

Riassunto

La resa di frammenti di interesse astrofisico con 6≤A≤11 emessi in reazioni complesse di particelle α con i nuclei C, N, O dell'emulsione nucleare è stato determinata sperimentalmente ad energie vicine alla soglia di produzione. I prodotti di reazione sono stati identificati tramite un'analisi cinematica di ciascuna interazione. Le sezioni d'urto della produzione sono state calcolate ed è stato chiarito il contributo dei diversi canali di reazioni a ciascun isotopo.
