Evaporation mechanism and direct effect in n, p reactions on medium weight nuclei

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

Energy spectra of protons emitted in (n, p) reactions with 14 MeV neutrons on 13 nuclides from31P to103Rh are presented. The presence of both evaporation and direct mechanisms is put in evidence. By comparing the forward with backward spectra an evaluation of direct effect cross-section is given.

Riassunto

Sono presentati gli spettri di energia dei protoni emessi da 13 nuclei compresi tra il31P e il103Rh. Viene mostrata 1’esistenza dei due meccanismi di reazione: l’evaporazione statistica e l’effetto diretto. Confrontando la forma degli spettri dei protoni emessi in avanti con quelli emessi all’indietro si ottiene una valutazione della sezione d’urto dell’effetto diretto.
