Measurement of Neutron Capture Cross Section for 180Hf

摘要

正 The neutron capture cross section for 180Hf relative to the 197Au（n,γ）198Au reaction ismeasured at neutron energies of 0.52,1.10 and 1.60 MeV using the activation method.Theactivities of the products are measured with a high resolution HPGe detector gamma ray spec-trometer.The errors of the measured results are 5%～6%.Our results have a good agreementwith those of other authors within errors.Cross sections for the reaction are calculated withUNF code and recommended data are also given.
