Abstract

The evaporation residue (ER) cross sections for the reaction ${}^{19}F +^{187} R e \to^{206} P o^{⁎}$ 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 ( $β_{2}$ ) and effective fissility ( $χ_{e f f}$ ) are studied.

导致206Po复合核的准裂变反应的入口通道依赖性

在激发能86.1 ~ 118.4 MeV范围内，测量了F19+187Re→206Po的蒸发残馀(ER)截面。将实测截面与30Si + 176Yb反应的截面进行了比较。理论计算采用耦合通道计算捕获截面和统计模型计算的ER截面。研究了准裂变与入口通道参数如电荷积(Z1Z2)、质量不对称(α)、靶变形(β2)和有效裂变率(χeff)的关系。
