采用CS-30等时性回旋加速器制备放射性核素175Hf，173Hf和173Lu的研究

Based on our domestic experimental condition, CS-30 isochronous cyclotron could be considered to produce radionuclide 175Hf, 173Hf and 173Lu with a particle beam bombarded natural ytterbium. After irradiation, some special chemical procedures have been done for the ytterbium samples in order to reduce background caused by the decay of 65Zn, 67Ga and so on. g spectroscopy has been measured for a long time in order to obtain the information about the products of these nuclear reactions with low background HPGe spectrometer. Therefore, some data, such as branching ratio, half-life, have been obtained and the corresponding content of radioisotopes in sample has been obtained for some nuclear reactions with a particle different energy irradiation.
