Abstract:
Cross sections of 141Pr(n,gamma) 142Pr reaction are measured at neutron energies of 0.54, 1.09 and 1.59 MeV using the activation method. The activities of the products are counted with a high resolution HPGe detector gamma-ray spectrometer. The neutron fluence is determined by 197Au(n,gamma)198 Au reaction cross sections. The errors of the measured results are +/-6-7%. The neutron capture cross sections for this reaction are also calculated with the NUNF code. Our results are compared with those of other authors. Recommendations for inclusion of data in the energy region 0.05-3.90 MeV are made, these being in good agreement with the ENDF/B-VI data.
