摘要: 第一次测量到²³⁸U（⁹Be，5n）²⁴²Cm熔合蒸发反应的激发函数。通过使用叠层靶，在不改变束流能量的条件下，在线获得20个能量点下的实验数据。利用蒸发余核²⁴²Cm的半衰期较长，且衰变模式是α衰变的特点，用离线测量α放射性的方法得到目标核产额。实验最大截面约1 mb，激发函数曲线的形态和峰值所在的能量位置与现有的理论模型的计算结果一致。激发函数的实验数据对选择和优化理论模型，推动超铀核区核物理研究具有重要的意义。

The excitation function of the ²³⁸U(⁹Be, 5n) reaction was obtained for the first time. By using a stack of uranium targets, 20 experimental data were obtained by the on-line irradiation without changing beam energy. Taking the advantage of the long lifetime and α decay mode of the residue nucleus ²⁴²Cm, the off-line measurement of the α radioactive was performed to obtain its yields. The maximum cross section is about 1 mb. The curve's shape and the maximum's position agree with the present model. The value of the cross section will help us to develop the ralated models, and push the nuclear studies in the transuranium region.
