| Abstract: | An instrumental method for the simultaneous determination of selenium and ytterbium by thermal neutron activation analysis is described. Selenium and ytterbium were determined via the 400.7 keV photopeak of75Se and the 177 keV photopeak of169Yb. The accuracy of this instrumental method has been examined; as a result, it has been proved that this method is most exact and accurate when the gamma-ray counting is carried out after the decay of175Yb. |
