Measurement of partial gamma-ray production cross-sections and k0-factors for radionuclides with chopped-beam PGAA—Part II

As a continuation of our previously reported experiments, the partial gamma-ray production cross-sections (σγ) and k0-factors of 12 short- and medium-lived radionuclides were determined using a chopped beam of cold neutrons. This technique avoids several problems associated with epithermal activation, sample transportation and dead-time effects in neutron activation analysis (NAA) measurements. Our k0-values were determined with internal standardization, using stoichiometric compounds or water solutions of known compositions.
