Measurement of activation cross sections for the Sm-144(n,2n)Sm-143g reaction was performed by Cyclic Activation Method (CAM) around 14 MeV neutron energy. Natural samarium samples were irradiated by the neutrons produced by H-3(H-2,n)He-4 reaction using a neutron generator. Delayed gamma ray activities produced by fast neutrons in samples were measured by a high resolution gamma ray spectrometer [high-purity Germanium (HpGe) detector]. The measured cross sections are compared with the results of model calculation (STAPRE code) and evaluated data (JEFF 3.0/A).
