Description

For measuring (d,n) reactions, neutron detectors with n-γ pulse shape discrimination have been built. Neutron energy is determined by proton recoil spectra. For this purpose, several methods of calculation have been tested. For application of the equipment, the vector analyzing strength of the reactions 12C(d vector,nsub(0,1))13N and 28Si(d vector, nsub(0,1,2))29P was measured with a deuteron energy of Esub(d) = 11 MeV. The results were compared with DWBA calculations and with corresponding (d vector,p) reactions from literature. At the reactions 28Si(d vector,n1)29P and 28Si(d vector,n2)29P the vector analyzing strength could be shown to depend on j = l +- 1/2. (orig.)

Abstract (German)

Zur Messung von (d,n)-Reaktionen wurden Neutronendetektoren mit n-γ-Impulsformdiskrimination aufgebaut. Die Neutronenenergie wird aus den Protonenrueckstossspektren bestimmt. Dazu wurden mehrere Rechenverfahren erprobt. Zur Anwendung der Apparatur wurde die Vektoranalysierstaerke der Reaktionen C12(d vektor,nsub(0,1))N13 und Si28(d vektor,nsub(0,1,2)P29 bei einer Deuteronenenergie von Esub(d) = 11 MeV gemessen. Die Ergebnisse wurden mit DWBA-Rechnungen verglichen und mit entsprechenden (d vektor,p)-Reaktionen aus der Literatur. Bei der Reaktion Si28(d vektor,n1)P29 und Si28(d vektor,n2)P29 konnte die Abhaengigkeit der Vektoranalysierstaerke von j = 1 +- 1/2 gezeigt werden. (orig.)
