Summary
We propose and discuss a nonrelativistic solvable model for the pion pair photoproduction amplitude on a single nucleon. The results here obtained give a parametrization of the amplitude itself, which clarifies analogous parametrizations currently employed in the literature.
Riassunto
Si propone e si discute un modello non relativistico per l’ampiezza di fotoproduzione di coppie di pioni. I risultati ottenuti portano ad una parametrizzazione dell’ampiezza stessa che chiarifica il significato di analoghe parametrizzazioni normalmente in uso e ne specifica i limiti di validità.
Реэюме
Мы предлагаем и обсуждаем нерелятивистскую рещаемую модель для амплитуды фоторождения пионных пар на отдельном нуклоне. Полученные эдесь реэультаты дают параметриэацию зтой амплитуды, что проясняет смысл аналогичных параметриэаций, обычно испольэуемых в литературе.
