0233276WellerThis award supports Henry Weller, a junior faculty member, and two students from Duke University in a collaboration with Andreas Zilges of the Department of Nuclear Physics at the University of Darmstadt, Germany. The project will focus on determining the distribution of electric dipole strength close to the neutron threshold in nuclei. This strength has important implications for various nucleosynthesis processes. A combination of experiments using the intense white bremsstrahlung beam in Darmstadt and the completely linearly polarized monochromatic gamma-ray beam at Duke will allow for a systematic determination of the electric dipole strength distributions, provide complete decay schemes, and allow for unambiguous parity assignments. The collaboration will provide for the transfer of experimental expertise and equipment from the Darmstadt facility, which will help make the Duke facility a world-class facility.The project also has an educational objective. The project will allow the graduate students involved to benefit from performing research in another country. They will develop a heightened appreciation of the world around them while also learning important new technical skills.

0233276Weller 该奖项支持杜克大学的初级教员 Henry Weller 和两名学生与德国达姆施塔特大学核物理系的 Andreas Zilges 合作。 该项目将重点确定接近原子核中子阈值的电偶极子强度分布。 这种强度对各种核合成过程具有重要意义。 使用达姆施塔特的强白色轫致辐射束和杜克大学的完全线偏振单色伽马射线束进行的实验相结合，将能够系统地确定电偶极子强度分布，提供完整的衰减方案，并允许明确的宇称分配。 此次合作将提供达姆施塔特设施的实验专业知识和设备的转让，这将有助于使杜克大学设施成为世界一流的设施。该项目还有一个教育目标。 该项目将使参与的研究生能够从在另一个国家进行的研究中受益。 他们将提高对周围世界的欣赏能力，同时学习重要的新技术技能。
