Abstract：
Three fragments emitted from the decay of hot nuclei formed in central collision of 25MeV/u ⁴⁰Ar with ¹⁵⁹Tb、 ¹⁹⁷Au、 ²⁰⁹Bi were measured coincidently.In these cases,the corresponding excitation energy of hot nuclei is about 3MeV/u.The distributions of the mass,the relative angle and relative velocities are obtained by correlation measurement.The probability ratio of ternary fission relative to binary fission in detector space has been modified to 4π geometry in terms of Monte-Carlo method.
