Summary
A problem consisting of two coupled channels is considered, and it is shown that the use of a one-channelN-over-D method, with the inelasticity introduced through the factorR in the unitary relation Ima = R¦a¦2, does not necessarily give the correct solution.
Riassunto
Si studia un problema costituito da due canali accoppiati, e si dimostra che l’uso del metodoN suD di un canale, in cui l’anelasticità è introdotta per mezzo del fattoreR nella relazione di unitarietà Im« =R¦a¦ 2, non dà necessariamente la giusta soluzione.
