几种稀土金属自支撑靶膜的制备及其保存
THE PREPARATION AND PRESERVATION OF FIVE KINDS OF RARE-EARTH METAL SELF-SUPPORTING TARGET FOIL
【摘要】 在新核素合成、153Er(EC+β+)研究、三裂与核温度测量、中能重离子碰撞中巨共振实验中,需要稀土Nd、Yb、La、TI.Gd金属自支撑靶膜,要求厚度为0.8mg/cm2以上,靶孔为15—30mm。采用液压方法进行这几种靶的制备。该法对面密度大于1mg/cm2金属自支撑靶的制备是一种十分有效的方法,其优点是所用的原始材料少、材料利用率高、靶膜不受设备等条件的污染、纯度高(只取决于初始材料的纯度)、膜的机械性能好、能经受较长时间的离子束轰击等。现已成功制备出Yb、Nd、La、Tb、Gd稀土金属自支撑靶,并实验探讨了它们在不同条件下的氧化情况。
【Abstract】 The concrete preparing process of rare-earth element Nd. Yb. La. Tb. Gd melalllc self-supporting target foils by the rolling method are described, The characteristic of the target foils are analysed. The preservation condition of target foils are also discussed with the results of experiment. Now, the above target foils are successfully used in the experiments of new nuclide synthesis, the(EC + β) decay of 153 Er, etc.
