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

0233276 Weller该奖项支持德国达姆施塔特大学核物理系的Andreas Zilges与杜克大学的初级教师亨利韦勒和两名学生合作。 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分布。 这种强度对各种核合成过程具有重要意义。 结合实验使用强烈的白色韧致辐射束在达姆施塔特和完全线性偏振的单色γ射线束在杜克将允许一个系统的电偶极子强度分布的测定，提供完整的衰变计划，并允许明确的奇偶分配。 这项合作将提供从达姆施塔特实验室转移的实验技术和设备，这将有助于使杜克实验室成为世界一流的实验室。该项目还具有教育目的。 该项目将使参与的研究生能够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赞赏，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.
