Summary
Theoretical calculations are carried out on π- -α. and π+-α elastic scattering processes. Results are presented at a typical incident pion energy of 100 MeV. The results are sensitive to the pion’s electromagnetic form factor since the form factor of the a-particle may be taken from electron scattering experiments. If the pion size is large the burden on the theoretical calculations is not great. However if the pion size is small the calculations must be refined. In any case the comparison ofK a andn a scattering is quite worth while and suggestions are made on how to carry it out.
Riassunto
Si fanno calooli teorici sui processi di scattering elastico {ie1860-01} Si presentano i risultati per una energia tipica del pione incidente di 100 MeV. I risultati sono influenzati dal fattore di forma elettromagnetico del pione, poichè il fattore di forma della particella α può essere dedotto dagli esperimenti di scattering dell’elettrone. Se la dimensione del pione è grande la complessità dei calcoli teorici non è grande. Invece se la dimensione del pione è piccola’i calcoli devono essere ramnati. In ogni caso il confronto dello scattering {ie1860-02} abbastanza interessante e si suggerisce corne farlo.
