标题： Relaxation of fast collective motion in heated nuclei

摘要： 研究了高温原子核中集体振动的阻尼效应，采用半经典的Vlasov-Landau运动论理论。 利用耗散独立源方法的扩展形式，并通过混沌加权壁公式，允许不可逆的能量转移。 得到了巨多极共振固有宽度的表达式。 讨论了一体和二体通道之间的相互作用，这些通道有助于形成核的固有宽度。 显示英文摘要

摘要： The damping of the collective vibrations in hot nuclei is studied within the semiclassical Vlasov-Landau kinetic theory. The extention of the method of independent sources of dissipation is used to allow for irreversible energy transfer by chaos weighted wall formula. The expressions for the intrinsic width of the giant multipole resonances are obtained. The interplay between the one-body and the two-body channels which contribute to the formation of the intrinsic width in nuclei is discussed.
