Summary
A model is presented in which the forces due to the presence of an inelastic channel with several spin degrees of freedom cause two different partial-wave phase shifts to go through 90° at the same energy, while a third partial-wave amplitude goes through resonance at two distinct energies. All the resonances occur below the inelastic threshold.
Riassunto
Si presenta un modello in oui le forze dovute alla presenza di un canale inelastico con molti gradi di libertà dello spin fanno si che due differenti spostamenti di fase dell’onda parziale ruotino di 90° alla stessa energia, mentre una terza ampiezza dell’onda parziale passa per la risonanza a due distinte energie. Tutte le risonanze avvengono sotto la soglia anelastica.
