The experimental results of sequential fission are presented for collision of ~(238)U (5.4MeV/u) on ~(48)Ca, ~(45)Sc and ~(238)U(6.0 MeV/u)on ~(16)O, ~(27)A1,~(48)Ca, ~(45)Sc, ~(48)Ti,~(58) Fe, ~(64)Ni and ~(89)Y targets. The measurements of ternary events in exit channel have been performed by triple coincidence among 4 PPAC with area of 20 cm×30 cm. The reconstruction of ternary events are performed by direct kinematics and the fission partner among three fragments is identified by relative velocities between them. The detection geometry efficiency is determind by a Monte-Carlo simulation.Before the sequential fission, U-like fragments are scattered near grazing angle. The most probable value of TKEL in the scattering process associated with S. F. changes from 25MeV to 55MeV for different reaction systems. The angular distributions of debris of S. F. in second C. M. are isotropic.In conclusion, because of lower fission threshold at Uranium region, the sequential fission mainly follows quasielastic scattering, in S. F. cross-section σ_(S.F.), there is strong shell effect. A simple relationship between σ_(S.F.) over σ_R, the total reaction cross-section and Sommerfeld parameters S for nuclei with magic number are obtained.

本实验测量了~(238)U(5.4MeV/u)轰击~(48)Ca、~(45)Sc靶和~(238)U(6.0MeV/u)轰击~(16)O、~(27)A1、~(48)Ca、~(45)sc、~(48)Ti、~(58)Fe、~(64)Ni及~(89)Y靶等10个反应系统的三体碎片符合出射道。得到了跟随裂变截面、总动能损失、碎片动能和质量分布以及碎片在第一质心与第二质心的角分布等。实验用了4片200ram×300mm的双维位敏雪崩计数器,给出了关联的空间位置信息与飞行时间。三体事件用运动学直接求解,其中识别裂变对碎片是基于该对之间相对速度为2.4cm/ns的事实。探测几何效率用蒙特卡罗模拟计算来确定。实验表明,跟随裂变源于准弹性散射,其截面σ_(S·F)较大,对于~(27)Al靶,σ_(S·F)为总截面的15%,而~(89)Y靶为70%。同时发现,对于幻核靶,σ_(S·F)与索末费尔得参数之间有简单的线性关系。

A unified parametrized formula of total reaction cross section σR from low energy to intermediate and high energy has been proposed.
