标题： Formation of Few-Body Clusters in Nuclear Matter

摘要： 从一个适当地修改过的三体方程出发以包含主要的介质效应（如自能修正和泡利阻塞），我给出了几个与重离子碰撞中轻团簇形成相关的可观测量的结果。 正确考虑介质会导致Mott效应，更大的反应速率，进而更快的氘核寿命和化学松弛时间尺度。 在一个用于模拟重离子反应的Boltzmann-Uehling-Uhlenbeck方法中，由于进入碰撞积分的基本截面中的介质效应，氘核的总数以及能量谱也发生了显著变化。 显示英文摘要

摘要： Starting from a suitably modified three-body equation to include dominant medium effects such as self energy corrections and Pauli blocking I present results on several observables relevant for the formation of light clusters in a heavy ion collision at moderate energies. Properly taking into account the medium leads to the Mott effect, larger reaction rates, in turn, faster time scales for the deuteron life time and chemical relaxation time. Within a Boltzmann-Uehling-Uhlenbeck approach to simulate the heavy ion reactions, also the total number of deuterons and the energy spectrum are significantly changed due to medium effects in the elementary cross sections entering into the collision integrals.
