摘要 60MeV/u18O离子与232Th反应产生放射性Ba同位素。通过3次BaCl2沉淀,将Ba从大量的Th和其他反应产物混合物中分离出来。使用离线!谱学方法完成Ba样品!活性的测量。根据各个Ba同位素的特征!射线峰的活度和其他相关数据,得到Ba同位素的产生截面。 The radioactive Ba isotopes are produced in the interaction of 60 MeV/u 18O ions with 232Th. Ba is separated from thorium and the reaction product mixture by using BaC12 precipitation. The y-ray spectra of the Ba fractions are measured by offline y-ray spectroscopy. The cross sections of the individual Ba isotopes are obtained based on the intensities of the characteristic y-ray peaks of Ba isotopes and other relative information.
