标题： Dynamics of dissipative binary collisions

摘要： 在本文中，我们讨论了在中间能量下半偏重离子碰撞的重叠区域发生的反应机制。 特别是我们关注颈部不稳定性的发展，这可能导致动态波动的可能增加。 如最近的实验数据所示，在束流能量略高于10 MeV/A时，最相关的预期结果是获得投影类似和靶类似可观测量的大方差的可能性。 随着束流能量的增加，我们进入中间快速度碎片生成。 这样，我们预测从非弹性到碎片化反应机制的平滑过渡。 显示英文摘要

摘要： In this paper we discuss the reaction mechanisms that occur in the overlap zone for semi-peripheral heavy ion collisions at intermediate energies. In particular we focus on the development of neck instabilities, that could determine a possible increase of dynamical fluctuations. As observed in recent experimental data, at beam energies just above 10 MeV/A the most relevant expected consequence is the possibility to obtain large variances in the projectile-like and target-like observables. With increasing beam energy we pass to a mid-rapidity fragment production. In this way we predict a smooth transition from a deep-inelastic to a fragmentation reaction mechanism.
