|
The measurement of gamma-ray spectrum of nat W(p,xn) reaction with natural tungsten were performed by using a high energy proton generated from a 100-MeV proton linear accelerator of the Korea Multi-purpose Accelerator Complex (KOMAC). Gamma rays generated by various nuclides generated through the nuclide were measured using a gamma-ray spectroscopy system composed of HPGe detector. A gamma-ray standard source was used for energy calibration and efficiency measurement of the detector. Analysis of the gamma rays observed in the measured spectra showed that the radionuclides produced were 167 Re, 178 Re, 179 Re, 180 Re, 181 Re, 182 Re, 184 Re, 172 Ta, 174 Ta, 178 Ta, 182 Ta, 184 Ta, 175 W, 176 W, 177 W and 179 W. Nuclides were generated. The results of this study will be applied to nuclear fusion, astrophysics, and nuclear medicine applications in the future.
