Summary

The forward photoproduction of π±Δ is studied in a Coulomb-coupling approximation. It is shown that the prescription suggested by Dombey for the choice of the Coulomb coupling fails to work in these reactions. A way in which these difficulties may be overcome is suggested and this model succeeds in explaining many features of these reactions rather well.

Riassunto

Si studia la fotoproduzione in avanti nell’approssimazione dell’accoppiamento coulombiano. Si dimostra che la prescrizione suggerita da Dombey per la scelta dell’accoppiamento coulombiano non è valida in queste reazioni. Si indica come superare queste difficoltà e questo modello riesce a spiegare abbastanza bene diverse caratteristiche di queste reazioni.

Реэюме

Исследуется фоторождение в направлении вперед для π±Δ в приближении кулоновской свяэи. Покаэывается, что рецепт, предложенный Домбеем для выбора кулоновской свяэи не работает в зтих реакциях. Предлагается путь, который поэволяет преодолеть зти трудности. Эта модель довольно хорощо общясняет многие особенности зтих реакций.
