标题： Instabilities in Nuclei

摘要： 在Vlasov方程的框架下研究了核多重碎裂中动力扰动的演化。 在存在表面（Yukawa）力的情况下，研究了平面波和气泡型的扰动。 给出了允许的不稳定性类型的能量条件，并计算了不稳定性指数增长的时间尺度。 结果与机械自旋分解区域的预测进行了比较。 PACS: 25.70 Mn 显示英文摘要

摘要： The evolution of dynamical perturbations is examined in nuclear multifragmentation in the frame of Vlasov equation. Both plane wave and bubble type of perturbations are investigated in the presence of surface (Yukawa) forces. An energy condition is given for the allowed type of instabilities and the time scale of the exponential growth of the instabilities is calculated. The results are compared to the mechanical spinodal region predictions. PACS: 25.70 Mn
