0336518ElsterThis award supports Charlotte Elster and students from Ohio University in a collaboration with Siegfried Krewald of the Institute of Nuclear Physics at the Research Center in Juelich, Germany. The research will focus on developing a model of the exchange of the vector mesons omega and rho, the nucleon exchange, and S-wave resonance. By studying the effect of different production mechanisms on polarization observables, suggestions for possible experimental investigations will become possible. Since the eta-prime photoproduction from the deuteron is close to the production threshold, it will also be possible to study the effects of the meson-nucleon final-state interaction. Extensive experience with many aspects of the nucleon-nucleon interaction, along with a history of developing meson-nucleon interactions, allows the US-German collaboration to include sophisticated final-state interaction into photoproduction calculation. The combined complementary expertise that the two sides bring to bear creates an ideal environment for carrying out the proposed research project and for training junior researchers in an international setting.

0336518埃尔斯特这个奖项支持夏洛特埃尔斯特和学生从俄亥俄州大学在合作与齐格弗里德Krewald的研究中心的核物理研究所在Juelich，德国。 这项研究的重点是建立矢量介子Ω和ρ交换、核子交换和S波共振的模型。 通过研究不同产生机制对偏振观测值的影响，为可能的实验研究提出建议。 由于来自氘核的η-素数光生接近产生阈值，因此也有可能研究介子-核子末态相互作用的影响。 在核子-核子相互作用的许多方面的丰富经验，沿着发展介子-核子相互作用的历史，使美国和德国的合作，包括复杂的末态相互作用的光生计算。 双方结合互补的专业知识，为开展拟议的研究项目和在国际环境中培训初级研究人员创造了理想的环境。
