Summary
The effect ofN N annihilation on antiproton-nucleus scattering has been studied by use of phenomenologicalN N annihilation potential. The results indicate that at small angle the effect makes no difference but for large angles it plays an important role in solving the discrepancies between theory and existing data available.
Riassunto
Si è studiato l’effetto dell’annichilazione diN N sullo scattering tra antiprotone-nucleo con l’uso del potenziale di annichilazione diN N fenomenologica. I risultati indicano che ad un angolo ridotto l’effetto non fa alcuna differenza, ma per angoli ampi gioca un ruolo importante nel risolvere le discrepanze tra la teoria e i dati disponibili esistenti.
Резюме
Используя феноменологический потенциалN N аннигиляции, исследуется влияниеN N аннигиляции на рассеяния антипротонов на ядрах. Полученный результат показывает, что при малых углах эффект пренебрежимо мал, а при больших углах играет важную роль в обьяснении расхождений между теорией и имеющимися экспериментальными данными.
