【摘要】 本文假定在断裂过程中碎片相对运动动能可以忽略,绝热近似条件得到满足,并且碎片只有旋转对称的四极形变,从而得到决定断点处碎片运动的三个方程。求解这一简单的代数方程组,可以得到断点拉长度,并得到出射碎片的总动能。计算结果与重离子引起的融合裂变和准裂变(深部非弹性散射的全阻尼)过程中出射碎片的平均总动能的许多实验资料符合。更多还原

【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.更多还原
