Reaction with Exotic Nuclei: Toward a Microscopic Theory

中子或质子过量的核可以在加速器中产生，并表现出奇异的性质，其中一些对天体物理学至关重要。这些不稳定核的性质可以通过与稳定靶的反应来提取。很明显，为了确定这些原子核的结构，我们需要可靠的反应模型。这些模型应该从一开始就考虑到奇异原子核的真实情况。这些不稳定核最重要的一个方面是它们非常容易分裂。在核反应模型中通常进行几种简化。一种有争议的假设是奇异核（抛射体）行为是两个惰性碎片，结合在一起，很容易分裂。在这个项目中，我们将发展一个新的反应模型，超越这个近似。这个新的模型将在对射弹的描述中加入更多的细节，使其所有部分都能动态地感受到目标的影响，作为对反应进行微观处理的一步。

Nuclei with a large neutron or proton excess can beproduced in accelerators and exhibit exotic properties,some of which are crucial for Astrophysics.The properties of these unstable nuclei can be extracted throughreactions with stable targets. It is then clear that, in orderto determine the structure of these nuclei, one needs reliablereaction models. These models should take into account, fromthe start, a realistic picture of the exotic nucleus. One of themost important aspects of these unstable nuclei is the factthat they break up very easily.Several simplifications are usually performed in nuclear reaction models.A questionable one is the assumption that the exotic nucleus (projectile)behaves are two inert fragments, bound together, which can easily breakup.In this project we will develop a new reaction model that goes beyondthis approximation. This new model will incorporate more detail in thedescription of the projectile, allowing all its parts to dynamicallyfeel the influence of the target, as a step toward a microscopictreatment of the reaction.
