New determinations of gamma-ray line intensities of the $E_P$=550 and 1747 keV resonances of the $^{13}C(P,\gamma)^{14}N$ reaction
Résumé
Gamma-ray angular distributions for the resonances at Ep = 550 keV and 1747 keV of the radiative capture reaction 13-C(p,g)14-N have been measured, using intense proton beams on isotopically pure 13-C targets. Relative intensities for the strongest transitions were extracted with an accuracy of typically five per cent, making these resonances new useful gamma-ray standards for efficiency calibration in the energy range Egamma = 1.6 to 9 MeV.
