Description

(p,α) reactions on the target nuclei 20Ne, 24Mg, and 26Mg in the energy range between 22.5MeV and 45 MeV to different final states were studied. The comparison of the measured angular distributions with finite-range DWBA calculations in the cluster-approximation shows that an optimal reconstruction of the measured angular distributions is possible with similar potential parameters for the optical α-potential, which were already successfully applied to earlier performed analyses of the reactions 11B(p,α) and 19F(p,α), while the potential data obtained from scattering experiments could not be applied. The measured strengths for the single transitions are comparable both to the experimental strengths for the one-particle transfer and to the results from shell-model calculations. (orig./HSI)

Abstract (German)

Es wurden (p,α)-Reaktionen an den Targetkernen 20Ne, 24Mg und 26Mg im Energiebereich zwischen 22,5 MeV und 45 MeV zu mehreren Restkernzustaenden untersucht. Der Vergleich der gemessenen Winkelverteilungen mit finite-range DWBA-Rechnungen in der Clusternaeherung zeigt, dass eine optimale Wiedergabe der gemessenen Winkelverteilungen mit aehnlichen Potentialparametern fuer das optische α-Potential gelingt, die bereits bei frueher durchgefuehrten Analysen der Reaktionen 11B(p,α) und 19F(p,α) mit Erfolg verwendet wurden, waehrend aus Streuexperimenten gewonnene Potentialdaten dazu nicht in der Lage sind. Die gemessenen Staerken fuer die einzelnen Uebergaenge lassen sich sowohl mit den experimentellen Staerken fuer den Einteilchentransfer als auch mit Ergebnissen aus Schalenmodellrechnungen vergleichen.
