摘要：
An extended time-dependent Hartree-Fock theory which includes the effects of nucleon-nucleon collisions is presented and applied to the small-amplitude quadrupole motions of16O and40Ca. The collision term of the theory includes not only the Born term but also higher-order terms. It is found that the higher-order terms are essential to the damping of the motions. © 1990 Springer-Verlag.
