Summary
Using the results of the calculation in Part I, a method suggested by Chew is applied to low-energy π-A scattering in order to relate the residues of the true Σ and true Y1* poles. The result is γY1*≈3/4γΣ; this numerical relation is in rough agreement with the numbers used in Part I and with experimental information now available for these residues.
Riassunto
Servendosi dei risultati del calcolo eseguito nella Parte I, si appllca allo scattering π-A di bassa energia un metodo suggerito da Chew allo scopo di mettere in relazione i residui del vero polo Σ e del vero polo Y1*. Il risultato é γY1*≈3/4γΣ; questa relazione numerica é in grossolano accordo eon i numeri usati nella Parte I e con i dati sperimentali attualmente disponibili su questi residui.
