摘要：

Damping of nuclear collective vibrations is studied on the basis of a Boltzmann-type transport equation with memory effects. It is shown that the memory effects play an essential role for a proper treatment of the damping properties of collective vibrations. A simple analytical formula is derived for the spreading widths at finite temperatures which provides a reasonable description for the gross properties of the damping of giant dipole and giant quadrupole resonances over a broad range of nuclei.
