U.S.-Germany Cooperative Research: The Study of Helicity Structure of Photoreactions on Deuterium and Helium-3

0124689 Weller该奖项支持亨利韦勒和杜克大学的学生与德国美因茨大学核物理研究所的汉斯·阿伦兹合作。 该项目将侧重于测量Gerasimov-Drell-Hearn求和规则对氘核的有效性。 低能量部分或测量将在美国进行，由德国小组参与，测量的高能量部分将在德国的美因茨微波加速器上进行。 测量将比较中子和质子的求和规则与氘核的求和规则，这两种情况都需要高能和低能测量。 合作的可能继续可以致力于测量氦-3的求和规则。 工作计划规定研究生广泛参与国际旅行和研究。

0124689WellerThis award supports Henry Weller and students from Duke in a collaboration with Hans Arends of the Institute for Nuclear Physics at the University of Mainz, Germany. The project will focus on measuring the validity of the Gerasimov-Drell-Hearn sum rule for the deuteron. The low-energy part or the measurement will be performed in the US, with participation by the German group, and the high-energy part of the measurement will be performed on the Mainz Microtron in Germany. The measurements will compare the sum rules on the neutron and proton to that on the deuteron, for which both high- and low-energy measurements are required. A possible continuation of the collaboration could then work on measuring the sum rule for Helium-3. The work plan provides for extensive participation by graduate students in the international travel and research.
