在２０°至１５５°范围内测量了２５ＭｅＶ／ｕ的４０Ａｒ轰击１５９Ｔｂ靶产生的单举中等质量碎片（３≤Ｚ≤９）能谱．后角区中等质量碎片能谱具有明显的统计蒸发特性，不同元素的能谱可用相同参数的单个运动源模型很好地拟合．拟合提取的源速度和核温度等源参数与非完全熔合所形成热核的反冲速度和核温度近似一致，表明这些不同的中等质量碎片共同起源于热核的统计蒸发．使用统计程序ＧＥＭＩＮＩ计算了碎片角分布和电荷分布．
Spectra were measured from a 25ArV / u 40Ar bombardment 159Tb target generated single-shot mid-quality fragment (3≤Z≤9) in the range of 20 ° to 155 °. The energy spectra of the medium-quality fragments in the post-corner region have obvious statistical evaporation characteristics, and the energy spectra of different elements can be well fitted by a single motion source model with the same parameters. The source parameters such as source velocity and core temperature of the fitting and extraction are approximately the same as the recoil velocities and core temperatures of the thermonuclear nuclei formed by incomplete fusion, indicating that these different middle-quality fragments all originate from the statistical evaporation of the thermonuclei. The statistical procedure GEMINI was used to calculate the angular distribution of the fragments and the charge distribution.
