Summary
The complex potential for neutrons in an infinite nuclear medium is computed in a perturbation calculation up to the second order, using for the nucleon-nucleon interaction a regular potential which fits the low energy two-body data. It is shown that it is possible to fit simultaneously the real and the imaginary part of the optical potential and the binding energy of the nuclear matter at normal density. Some arguments for the convergence of the theory are given.
Riassunto
Con un caloolo delle perturbazioni fino al secondo ordine si caleola il Potenziale complesso per i neutroni in un mezzo nucleare infinito, assumendo per l’interazione nucleone-nucleone un Potenziale regolare soddisfacente i dati dell’interazione a bassa energia fra due corpi. Si dimostra che è possibile soddisfare contemporaneamente le parti reale e immaginaria del potenziale ottico e l’energia di legame della materia nucleare di densità normale. Si danno alouni argomenti a favore della convergenza della teoria.
