Abstract：
Assuming that the kinetic energy of relative radial motion of fragments can beneglected during the scission process, so that the adiabatic approximation condition isassumed to be fulfilled, and the fragments have rotationally symmetric quadrupole de-formation only. We have obtained three equations, which govern the motion of the frag-ments at scission point. Solving these simple algebra equations, we can obtain thescission point stretch, and evaluate the total kinetic energy of the emitted fragments.The calculated results are in agreement with most experimental data for the averagetotal kinetic energy of fragments for heavy nuclei, which are emitted in the process offusion-fission and quasi-fission i.e. completё damping process of DIS induced byheavy-ions.
