用核化学方法测量了入射能量为４７ＭｅＶ／Ａ１２Ｃ离子轰击铯靶的超靶产物钡的生成产额，并用放射化学分离方法和离线γ谱方法进行确定。从测量结果可知，获得的超靶产物的截面都比较大（与低靶产物相比）。而且钡同位素的分布峰位的最可几质量数为Ａｐ＝１２９．７±０．２，其分布宽度参数σＺ＝２．７６±０．２８
The formation yield of barium was measured by nuclear chemistry method with the incident energy of 47 MeV / A12C bombarded with cesium target. The yield of barium was determined by radiochemical separation method and off-line γ spectrometry. As can be seen from the measurement results, the cross section of the obtained super-target product is relatively large (compared with the low target product). Moreover, the most probable mass peak of the distribution of barium isotopes is Ap = 129.7 ± 0.2, and the distribution width parameter σZ = 2.76 ± 0.28
