This grant supports research in nuclear astrophysics and nuclear physics. The nuclear astrophysics work involves study of nuclear reactions involving radioactive nuclides. Some of these reactions are of importance to primordial nucleosynthesis, as they determine the possibility of making nuclides heavier than carbon in the big bang. Others impact the Hot CNO cycle, in that they describe the ability of that stellar burning process to generate energy or synthesize nuclides heavier than oxygen. The nuclear physics component involves a search for a new type of reaction mechanism involving resonant pion transfer between analog nuclei at energies near the coulomb barrier. Both the nuclear physics and the nuclear astrophysics studies utilize experimental facilities at Notre Dame University and at Livermore National Laboratory which allow studies of reactions on the radioactive nuclei of interest by a double scattering technique.

这笔赠款支持核天体物理学和核物理学的研究。 核天体物理学工作涉及涉及放射性核素的核反应的研究。 其中一些反应对于原始核合成非常重要，因为它们决定了在大爆炸中制造比碳更重的核素的可能性。 其他影响热碳氮氧循环的因素是，它们描述了恒星燃烧过程产生能量或合成比氧重的核素的能力。 核物理部分涉及寻找一种新型反应机制，涉及模拟核之间以接近库仑势垒的能量进行共振π介子转移。 核物理和核天体物理研究均利用圣母大学和利弗莫尔国家实验室的实验设施，通过双散射技术研究感兴趣的放射性核的反应。
