Abstract：
Taking into account of the effect of deformation and using the scission point equations and equal-temperature condition, the formula for estimating excitation energy of fragments in fusion-fission and quasi-fission induced by heavy-ions is obtaind in this paper. When the quadrupole deformation coefficients α₁=α₂=0, the equation returns to the well-known formula E₁^*/E₂^*=A₁/A₂.
