摘要：
The evaporation residue (ER) cross sections for the reaction F-19 +Re-187 ->(206) Po* are measured, in the excitation energy range of 86.1 to 118.4 MeV. The measured cross sections are compared with that of Si-30 + Yb-176 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 (Z(1)Z(2)), mass asymmetry (alpha), target deformation (beta(2)) and effective fissility (chi(eff)) are studied.
