Abstract :
Gamma-ray angular distributions for the resonances at Ep=550 and 1747 keV of the radiative capture reaction 13C(p,γ)14N have been measured, using intense proton beams on isotopically pure 13C targets. Experimental gamma-ray spectra were obtained with three HP–Germanium detectors at four angles for Ep=550 keV and six angles for Ep=1747 keV in the range of 0–90° with respect to the proton beam. From the data, relative intensities for the strongest transitions were extracted with an accuracy of typically 5%, making these resonances new useful gamma-ray standards for efficiency calibration in the energy range from Eγ=1.6–9 MeV. Gamma-ray branching ratios were obtained for several levels of 14N and are compared with literature values.
