Summary
A solution is constructed for the nonlinear integral equation of the effective πN scattering amplitude in nuclear matter. The Pauli blocking effect is considered at any order. The threshold valueC 0 is reproduced correctly at ϱ → 0, for increasing densitiesC 0 decreases by the Pauli blocking as in the LLEE effect.
Riassunto
Si costruisce una soluzione dell’ equazione integrale non lineare per l’ampiezza efflcace πN in materia nucleare. L’effetto del Woccaggio di Pauli è considerato ad ogni ordine. II valore di C0 alia soglia è riprodotto correttamente per ϱ→ 0. A densita crescenti il bloccaggio di Pauli fa diminuire C0 come nell’ effetto LLEE.
Резюме
Конструируется решение для нелинейного интегрального уравнения для эффективной амплитуды πN рассеяния в ядерном веществе. В каждом порядке рассматривается эффект блокировки Паули. При ϱ → 0 правильно воспроизводится пороговое значение С0. При увеличении плотности величина С0 уменьшается из-за блокировки Паули, как в эффекте LLEE.
