标题： Dynamics and Instabilities of Nuclear Fermi Liquid

摘要： 费米液体的运动学理论被应用于有限核。 核集体运动用可观测变量来描述：粒子密度、电流密度、压力等。 核动力学受到费米面变形（FSD）效应的强烈影响。 热核中集体运动的弛豫和巨多极共振的宽度由于碰撞积分中的记忆效应表现出与温度饱和的行为。 核费米液体的体积和表面不稳定性的发展对费米面变形（FSD）和弛豫过程等动态效应非常敏感。 由于费米面变形（FSD）效应，不稳定性增长率降低，并且依赖于粒子密度和表面涨落的多重性。 显示英文摘要

摘要： The kinetic theory of the Fermi liquid is applied to finite nuclei. The nuclear collective motion is treated in terms of the observable variables: particle density, current density, pressure etc. The nuclear dynamics is influenced strongly by the Fermi-surface distortion (FSD) effect. The relaxation of collective motion and the width of giant multipole resonances in hot nuclei show a saturated behaviour with temperature caused by the memory effect in the collision integral. The development of the bulk and surface instabilities of the nuclear Fermi-liquid is sensitive to the dynamic effects such as the FSD and the relaxation processes. The instability growth rate is reduced due to the FSD effect and depends on the multipolarity of the particle density and surface fluctuations.
