The (p, pα) and (α, 2α) reactions

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

The (p, pα) and (α, 2α) reactions furnish a useful tool for studying α-particle clustering within the nucleus. These reactions are discussed in terms of the momentum distribution function for the mass centre of the four nucleons to be knocked out as an α-particle and of the probability of finding the α-particle within the nucleus. The momentum distribution for the mass centre of the four nucleons within the nucleus is the same for both the reactions. The probability of finding the α-particle inside the nucleus in the (α, 2α) reaction is compared with the corresponding probability in the (p, pα) reaction.

Riassunto

Le reazioni (p, pa) e (α, 2α) forniscono un utile strumento per studiare l’agglomerarsi delle particelle a entro il nucleo. Si discutono queste reazioni in base alla funzione di distribuzione dell’impulso nel centre di massa dei quattro nucleoni che devono essere emessi come particella α e alla probabilitá di trovare la particella α entro il nucleo. La distribuzione dell’impulso nel centro di massa dei quattro nucleoni entro il nucleo è la stessa in entrambe le reazioni. Si confronta la probabilità di trovare la particella a entro il nucleo nella reazione (α, 2α) con la corrispondente probabilità nella reazione (p, pα).
