Abstract：
The splitting of hot nuclei into three massive fragments is analyzed by using a minimization procedure of difference between relative velocity and Coulomb repulsive velocity. It is utilized in ⁴⁰Ar+²⁰⁹Bi, ¹⁹⁷Au, ^l59Tb reactions at 25 MeV/u. The kinematics of ternary fragments emitted from excited nuclei with 3 MeV/u excitation energy produced by central collisions are presented. It is shown that the ternary fragments originate from two successive independent binary splitting. This result is also supported by the fact that experimental angular distributions of ternary fragments are nicely reproduced by sequential decays.
