Reactions allow for active exploration of nuclear properties, they play an important role in the evolution of the Universe and, further, they yield access to unique physical phenomena. Much of current research emphasis is on reactions with unstable nuclei, nuclei with a large neutron or proton excess. This project aims at understanding both central and peripheral reactions involving such exotic nuclei. Central reactions reveal the dependence of bulk nuclear properties on the neutron-proton content. Different peripheral reactions under scrutiny are doorways to various astrophysical processes as well as to the structure of the exotic nuclei of interest. Novel methods both for central and peripheral reactions will be advanced, establishing, in particular, links to mesoscopic phenomena elsewhere. Sensitivity to specific reactions will be explored in supernova simulations. This proposal will make an important contribution to the theoretical foundations of existing RNB experimental programs (such as the NSCL), as well as the studies planned for the new generation laboratories. In adition, the diverse nature of the project will allow to effectively engage the students at an early stage with nuclear research.

反应允许积极探索核性质，它们在宇宙的演化中起着重要作用，而且，它们提供了独特的物理现象的途径。目前许多研究的重点是不稳定核的反应，即中子或质子大量过剩的核。该项目旨在了解涉及这种外来核的中枢和外围反应。中心反应揭示了总体核性质对中子-质子含量的依赖性。不同的外围反应的审查是门户的各种天体物理过程，以及外来核的结构感兴趣。研究中心反应和外周反应的新方法将被提出，特别是建立与其他地方介观现象的联系。对特定反应的敏感性将在超新星模拟中探讨。这一建议将对现有的人民币实验项目（如国家科学院）的理论基础以及新一代实验室的研究计划做出重要贡献。此外，该项目的多样性将允许学生在早期阶段有效地参与核研究。
