This award supports a two-year collaborative research project between Professor Richard Boyd of Ohio State University and Dr. Isao Tanihata of the Institute of Physical and Chemical Research (RIKEN), Japan. The project is designed to measure cross sections using the radioactive beam facility at RIKEN, which are of interest to predictions of primordial nucleosynthesis. These predictions are crucial in testing the veracity of such models. The specific cross sections to be measured are aimed at improving our understanding of the primordial nucleosynthesis of nuclides somewhat heavier than those usually discussed in this context, but which are readily observable by astronomers, even at very low abundance levels. Also involved in the project are Professor James Kolata of the University of Notre Dame, and two postdoctoral fellows and one graduate student in Dr. Boyd's laboratory. All five scientists will undertake visits to RIKEN to carry out the project.

该奖项支持俄亥俄州立大学Richard Boyd教授和日本理化研究所（RIKEN） Isao Tanihata博士为期两年的合作研究项目。该项目旨在使用RIKEN的放射性束流设备测量横截面，这对预测原始核合成很感兴趣。这些预测对于检验这些模型的准确性至关重要。要测量的具体横截面旨在提高我们对核素的原始核合成的理解，这些核素比通常讨论的核素重一些，但天文学家很容易观察到。即使在非常低的丰度水平。参与该项目的还有圣母大学（University of Notre Dame）的詹姆斯·科拉塔（James Kolata）教授、博伊德博士实验室的两名博士后和一名研究生。所有五位科学家都将访问RIKEN以开展该项目。
