标题： Nuclear Shape Fluctuations in Fermi-Liquid Drop Model

摘要： 在核费米液体滴模型中，通过使用朗道-沃拉索夫-朗之万方程考虑了量子和热涨落。 核表面涨落的谱相关函数在一个不可压缩且无旋的费米液体的简单模型中进行了评估。 建立了谱相关函数与动态费米面畸变的依赖关系。 计算了特征振动变得过阻尼的温度。 结果表明，在现实的弛豫时间参数和高温区域，费米液体滴存在一个特定的本征模，其中恢复力仅由动态费米面畸变引起。 显示英文摘要

摘要： Within the nuclear Fermi-liquid drop model, quantum and thermal fluctuations are considered by use of the Landau-Vlasov-Langevin equation. The spectral correlation function of the nuclear surface fluctuations is evaluated in a simple model of an incompressible and irrotational Fermi liquid. The dependence of the spectral correlation function on the dynamical Fermi-surface distortion is established. The temperature at which the eigenvibrations become overdamped is calculated. It is shown that, for realistic values of the relaxation time parameter and in the high temperature regime, there is a particular eigenmode of the Fermi liquid drop where the restoring force is exclusively due to the dynamical Fermi-surface distortion.
