US-Germany Cooperative Research: International Collaboration Between HIGS and S-DALIC to Investigate the Dipole Strength in the Particle Threshold Region of Nuclei

0233276Weller该奖项支持初级教员Henry Weller和杜克大学的两名学生，他们与德国达姆施塔特大学核物理系的Andreas Zilges合作。该项目将侧重于确定原子核中接近中子阈值的电偶极子强度的分布。这一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韧致辐射光束和杜克大学的完全线偏振的单色伽马射线束的组合实验将允许系统地确定电偶极子强度分布，提供完整的衰变方案，并允许明确的宇称分配。这项合作将从达姆施塔特设施转移实验专业知识和设备，这将有助于使杜克设施成为世界级设施。该项目也有一个教育目标。该项目将允许参与的研究生从在另一个国家进行研究中受益。他们将培养对周围世界的高度欣赏，同时也学习重要的新技术技能。

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.
