Summary

We show the great sensitivity of the πd elastic-scattering observables to the details of the deuteron wave function. At 142 MeV and 256 MeV we find that the differential cross-section at θc.m.=180° depends linearly upon the quantityA(q2), which is the most important part of the deuteron electromagnetic form factor. A similar behaviour appears for the tensor polarizationt20(180°) at 142 MeV. Our results are compared with existing experimental data at backward angles.

Riassunto

Si mostra la grande sensibilità delle osservabili dello scattering elastico πd ai particolari della funzione d'onda del deuterone. A 142 MeV e a 256 MeV si trova che la sezione d'urto differenziale per θc.m.=180° dipende linearmente dalla quantitàA(q2), che è la parte più importante del fattore di forma elettromagnetico del deuterone. Un comportamento simile si osserva per la polarizzazione del tensoret20 (180°) a 142 MeV. Si confrontano i risultati con i dati sperimentali osservati per gli angoli all'indietro.
