The neutron resonance parameters and average capture cross section of 165Ho
Abstract
Neutron resonance scattering and capture measurements have been made on 165Ho(I = {7}/{2}) using a variety of sample thicknesses. On the basis of a χ 2 test, the spins of eight resonances have been assigned and five more given tentative spin assignments. An additional six resonances were given tentative spin assignments on the assumption that the Γ γ does not fluctuate significantly from resonance to resonance. The present results are compared with the assignments of other workers. The values of total radiation widths Γ γ do not show any significant fluctuations from the weighted mean value of 75.7±2.4 meV. The measurements of the average capture cross section from 0.5 keV to 100 keV are given, and these data are respectively lower than the published values of capture cross section (at 30 keV and 60 keV) obtained with a liquid scintillation tank and higher than the value (at 24 keV) obtained using an activation method. However, our data are in very good agreement with the Russian data obtained using the lead slowing down neutron spectrometer.
