Radionuclides are widely used in all areas of society , plays an irreplaceable role in the fields of agriculture, industry, medicine, and defense . Early radionuclides mainly from nature , with the accelerator and reactor development , the use of radionuclides to become the main way . Accelerator generation , research radioisotope has a reactor does not have the advantage of short-lived radionuclides , such as can be easily generated to study short-lived radionuclides , and the concern of literature research and existing domestic experimental conditions , the present paper identified the natural Yb α fusion reaction and natural Hf neutron activation reaction radionuclides . Experiment using isochronous cyclotron CS-30 alpha particle bombardment of natural the Yb target , get a variety of radioisotopes . In order to reduce the impact of 65Zn and 67Ga impurity measurement , radiochemical separation and purification of the irradiated target slice . At the same time , the use of 14 MeV neutron activation of natural Hf samples intense neutron generator , Hf, Lu radioisotope and irradiated samples measuring continuous tracking . After the irradiated samples was measured to obtain a large amount of information of some of the radionuclides . Analysis of the natural Yb α fusion the reaction 175Hf , 173Hf , 172Hf , 173Lu , 172Lu , and 175Yb γ-ray branching ratio , half-life, yield , and production cross section , and experimental data with B.Kirlaly group compared . Neutron activation obtained 175Hf , 173Lu , and 181Hf three kinds of radionuclide to obtain a branching ratio of these three nuclides , half-life , yield , and generate a cross-sectional , and were compared with the data in the database . The experimental data and methods to provide a reference for future experiments on the accelerator and the production of radioisotopes .
