Riassunto
Si determina la distribuzione angolare ed energetica delle particelle a risultanti dalla reazione27Al(n, α)24Na provocata da neutroni di 15.2 MeV. Le particelle vengono rivelate con emulsioni imcleari Ilford C-2 e K-0. La camera di reazione è stata progettata in modo da ottenere una buona delinizione angolare, tra 80‡ e 160‡. La distribuzione angolare risulta notevolmente anisotropa; la distribuzione energetica mostra un gran numero di particelle di bassa energia. Viene calcolata la temperatura del nucleo residuo e si discutono i risultati ottenuti.
Summary
The angular and energetic distribution of α-particles resulting from the27Al(n, α)24Na reaction produced by 15.2 MeV neutrons is determined. The particles are detected with Ilford C-2 and K-0 nuclear emulsions. The reaction chamber was designed so as to obtain a good angular definition, between 80‡ and 160‡. The angular distribution results remarkably anisotropic; the energetic distribution shows a great number of low energy particles. The temperature of the residual nucleus is calculated and the results obtained are discussed.
