A comment on the absolute determination of the spectroscopic factor in (d, p) sub-Coulombian reactions

Замечание об абсолютном определении спектроскопического фактора в (d, p) субкулоновских реакциях

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

A comparison is made between the spectroscopic factorS extracted from the40Ar(d, p)41Ar 1.354 MeV (3/2−) sub-Coulombian-stripping reaction and the one deduced from the analysis of the corresponding isobaric analog resonance. The dependence ofS on the neutron well geometrical parameters is investigated in detail. An effect due to the Nolen-Schiffer anomaly has been found in the investigation of the Coulomb displacement energy.

Riassunto

Si fa un confronto fra fattori spettroscopici estratti dalla reazione di stripping40Ar(d, p)41Ar 1.354 MeV (3/2−) sotto barriera Coulombiana e quelli dedotti dall'analisi della corrispondente risonanza analoga isobarica. Si studia in dettaglio la dipendenza diS dai parametri geometrici della buca di neutrone. Dal calcolo della «Coulomb displacement energy» si mette in evidenza un effetto dovuto all’anomalia di Nolen-Schiffer.

Резюме

Проводится сравнение спектроскопического фактораS, извлеченного из субкулоновской реакции сриппинта40Ar(d, p)41Ar 1.354 МэВ (3/2−), и спектроскопического фактора, полученного из анализа соответствующего изобарического аналогового резонанса. Подробно исследуется зависимостьS от геометрических параметров нейтронной ямы. При исследовании кулоновского смещения энергии обнаружен эффект, связанный с аномалией Нолена-Шиффера.
