Summary
An analysis of two resonances in the low-energy α-l2C scattering is made by Regge’s representation. It is shown that by one- and two-pole approximations all the relevant features of the process are satisfactorily described. The background integral appears to be negligible except near the forward direction. Some discrepancies met in previous analysis of this type are overcome. The results indicate that a Regge description for this process can be made successfully when there is no interference of too many resonances belonging to different trajectories.
Riassunto
Mediante la rappresentazione di Regge vengono analizzate due risonanze nello scattering α-12C a bassa energia. Si mostra che median te approssimazione ad nno e due poli si deaorivono soddisfacentemente tutte le prinoipali caratteristiche del processo. L’integrale di background è trascurabile tranne che per angoli molto vicini alia direzione in avanti. Vengono superate alcune discrepanze inoontrate in precedenti analisi di questo tipo ed i risultati indicano one si può descrivere alia Regge questo processo quando non C’è interferenza di troppe risonanze appartenenti a traiettorie diverse.
