Summary

Repulsive-core effects in two-nucleon transfer reactions are in vestigated by referring to the (t, p) stripping reactions. The form factor for the (t, p) stripping reactions is calculated by using a Tabakin potential for the neutron-proton interaction. We considered two different cases by taking for the repulsive and attractive parts of the Tabakin potential a Yamaguchi-type or a Breitet al. type parameter, It is found that the repulsive-core effects are important and should be taken into account to extract reasonable spectroscopic factors.

Riassunto

Si studiano gli effetti del nocciolo repulsivo nella reazione di trasferimento a due nucleoni con riferimento alle reazioni di stripping (t, p). Si calcola il fattore di forma per le reazioni di stripping (t, p) usando un potenziale di Tabakin per l'interazione neutrone-protone. Si sono considerati due casi differenti prendendo per le parti attrattive e repulsive del potenziale di Tabakin un parametro del tipo di Yamaguchi o del tipo di Breitet al. Si è trovato che gli effetti del nocciolo repulsivo sono importanti e dovrebbero essere presi in considerazione per estrarre fattori spettroscopici ragionevoli.

Резюме

Рассматривая реакции (t, p) стриппинга, анализируются эффекты, связанные с отталкивательным остовом в реакциях с обменом двумя нуклонами. Вычисляется форм-фактор для реакции (t, p) стриппинга, используя потенциал Табакина для взаимодействия нейтрона и протона. Мы рассматриваем два различных случая, учитывая отталкивательную и притягивающую части потенциала Табакина с помощью параметров Ямагучи или Брейта и др. Обнаружено, что эффекты, связанные сотталкивательным остовом, являются важными и должны учитываться, чтобы извлечь соответствуюшие спектроскопические факторы.
