Summary

For the reactions52Cr(d, p)53Cr and58Ni(d, p)59Ni predictions of the adiabatic model of Johnson and Soper (JS) for differential cross-sections, vector analysing powers and angular correlations have been compared to conventional DWBA analyses. Without readjusting of parameters, JS predictions can describe the reaction52Cr(d, p)53Cr as well as conventional analyses, whereas they fail in the case of58Ni(d, p) especially for the vector analysing power and the angular correlation. The JS predictions are found to be influenced remarkably by the nucleon optical potentials used to generate JS break-up potentials.

Riassunto

Per le reazioni52Cr(d, p)53Cr e58Ni(d, p)59Ni si sono confrontate le predizioni del modello adiabatico di Johnson e Soper (JS) per le sezioni d'urto differenziali, le capacità d'analisi vettoriale e le correlazioni angolari, con le analisi convenzionali di DWBA. Senza il riadattamento dei parametri, le predizioni di JS possono descrivere la reazione52Cr(d, p)53Cr altrettanto bene delle analisi convenzionali, mentre falliscono nel caso della reazino58Ni(d, p) specialmente per la capacità d'analisi vettoriale e la correlazione angolare. Si trova che le predizioni di JS sono influenzate notevolmente dai potenziali ottici dei nucleoni usati per generare i potenziali di rottura di JS.

Резюме

Для реакций52Cr(d, p)53Cr и58Ni(d, p)59Ni предсказания адиабатической модели Джонсона и Сопера для дифференциальных попепечных сечений, векторной анализирующей способности и угловых корреляций сравниваются с общепринятым DWVA анализом. Без подгонки параметров предсказания модели Джонсона и Сопера могут описать реакцию52Cr(d, p)53Cr, тогда как модель Джонсона и Сопера неприменима в случае58Ni(d, p), особенно для векторной анализирующей способности и угловой корреляции. Получено, что предсказания модели Джонсона и Сопера существенно зависят от нуклонных оптических потенциалов, использованных для получения потенциалов распада Джонсона и Сопера.
