Abstract：
The energy spectra and angular distributions of products(Z=4-14) emitted in reaction 156.3MeV ²⁸Si+ ¹²C were measured by using ΔE-E telescope detectors. Then Lorenz invariant cross sections of the products were presented. The most probable kinetic energy distributions E _l(θ) in the laboratory system and total kinetic energy E _t(Z) in the center of mass system were calculated for the products with Z=4—11,which indicates that these products come mainly from binary process. The complete fusion cross section was deduced to be (980±68)mb for this reaction system. The difference between this value and that extrapolated from the cross section at low energy may attribute mainly to the binary process.
