  • Published:
Il Nuovo Cimento A (1971-1996)

Summary

From relations between crossing behaviour andt-channel isospin of π scattering amplitudes we get some information about the shape of eikonal amplitudes in this process.

Riassunto

Dalle relazioni fra il comportamento di incrocio e l’isospin del canalet della ampiezza dello scattering π si ottiene qualche informazione sulla forma delle ampiezze iconali per questo processo.

Реэюме

Иэ свяэи между кроссинг-поведением и иэоспиномt-канала для амплитуд π рассеяния мы получаем некоторую информацию о форме зйкональных амплитуд в зтом процессе.

  8. This can be seen easily from formula (18) of ref. (3) and formulae (18) and (21) of ref. (8). Of course, the elastic amplitudes are different in both cases, therefore the fits may give different residue functions which influence the charge-exchange amplitudes.
