The evaporation residue (ER) cross sections for the reaction ${}^{19}F{+}^{187}Re{\to }^{206}P{o}^{⁎}$ are measured, in the excitation energy range of 86.1 to 118.4 MeV. The measured cross sections are compared with that of ³⁰Si + ¹⁷⁶Yb reaction populating the same compound nucleus. Theoretical calculations are performed using the coupled - channels calculations for the capture cross sections and statistical model calculations for the ER cross sections. The dependence of quasi fission on entrance channel parameters such as charge product (Z₁Z₂), mass asymmetry (α), target deformation (${\beta }_2$) and effective fissility (${\chi }_{eff}$) are studied.

206Po复合核反应中准裂变的入口通道依赖性

反应的蒸发残渣 (ER) 横截面${}^{19}F{+}^{187}右e{\to }^{206}磷{哦}^{⁎}$测量的激发能量范围为 86.1 至 118.4 MeV。将测量的横截面与填充相同化合物核的³⁰ Si + ^{176 Yb 反应的横截面进行比较。}理论计算是使用捕获横截面的耦合通道计算和 ER 横截面的统计模型计算来执行的。准裂变对入口通道参数的依赖性，例如电荷积 (Z ₁ Z ₂ )、质量不对称性 ( α )、目标变形 (${\beta }_2$）和有效裂变（${\chi }_{eFF}$）进行了研究。
