Abstract：
The velocities and angular distributions of fission partner emitted from reaction in ²⁸Si+¹⁹⁷Au system with energies from 5.5 up to 21.7MeV/A are measured.These results show that when the in cident energies are larger than 10MeV/A,the in complete fusion-fission (ICF) associated with in-complete momentum transfer (LMT) appears.Furthermore,when E_cm>200MeV,as a companion of ICF,the sequential fission (SF) with lower LMT than that of ICF,has apparent yields.By the difference of LMT for ICF and SF over total fission cross-section has been obtained.Meanwhile,the distribution around the reaction plane of one fragment with a standard deviation has been obtained.It seems that there is a simple linear global relationship between the deviation and excitation energy per nucleon in heavier composite systems.
