0305347KolataThis U.S.-Mexico award will support Dr. James J. Kolata of the University of Notre Dame in a research collaboration with Dr. Eli F. Aguilera of the Instituto Nacional de Investigaciones Nucleares (ININ) in Mexico City, Mexico. The researchers intend to work on reaction mechanisms in the interactions of weakly bound radioactive beams with normal nuclei. Research already carried out by the members of this collaboration has provided evidence for a number of rather dramatic new phenomena associated with "neutron-halo" systems affecting both the fusion and transfer/breakup cross sections. An extension of this program to directly investigate the neutron degrees of freedom in more detail is vital to achieving an understanding of these phenomena. In addition, it is natural to ask whether similar phenomena might occur in the interactions of "proton-halo" nuclei. The latter portion of the program will be carried out using the ATLAS linear accelerator at Argonne National Laboratory. Taken together, these two inter-related programs will lead to a much better understanding of the reaction mechanisms for and the structure of exotic, weakly-bound nuclear systems. This work will help to prepare the ground for research carried out with the next generation of radioactive nuclear beam (RNB) facilities in the US and abroad. The Office of International Science and Engineering and the Division of Physics of NSF are contributing funds for the research.

Kolata博士与Eli F.墨西哥墨西哥城国家核研究所（ININ）的Aguilera。 研究人员打算研究弱束缚放射性束与正常原子核相互作用的反应机制。这项合作的成员已经进行的研究提供了证据，证明了与影响聚变和转移/分裂截面的“中子晕”系统有关的一些相当引人注目的新现象。这个程序的扩展，直接调查的中子自由度更详细的是至关重要的，以实现这些现象的理解。此外，人们自然会问，在“质子-晕”核的相互作用中是否会发生类似的现象。 该计划的后一部分将使用阿贡国家实验室的ATLAS线性加速器进行。两者结合起来，这两个相互关联的程序将导致更好地理解的反应机制和结构的异国情调，弱约束核系统。这项工作将有助于为美国和国外下一代放射性核束（RNB）设施的研究奠定基础。 美国国家科学基金会国际科学与工程办公室和物理部为这项研究提供了资金。
