U.S.-Germany Cooperative Research: Nucleon Scattering from Very Light Nuclei at Intermediate Energy

该奖项支持国际和平研究所，夏洛特·埃尔斯特博士，博士后，以及俄亥俄大学的研究生，与波鸿鲁尔大学理论物理系的沃尔特·格勒克尔合作。这项合作将研究非常轻的核(2H，3He，4He)的性质，以及在中能(100 MeV及以上)弹性散射和分裂反应的反应机制。理论公式是基于描述包含少量核子的系统中的散射的方案。还将进行数值实现和关于高阶项的收敛的内部检查。合作的结果应该会为反应机制或轻核碰撞提供有趣的见解，并为测试各种物理假设奠定坚实的基础，例如自由核子-核子力在这些反应中的应用，以及轻核基态波函数的性质。

This award supports the PI, Dr. Charlotte Elster, a post doctoral student, and a graduate student from the Ohio University in a collaboration with Walter Gl`ckle of the Department of Theoretical Physics at the Ruhr University in Bochum. The collaboration will study the properties of very light nuclei (2H, 3He, 4He) and the reaction mechanism for elastic scattering and break-up reactions at intermediate energies (100 MeV and higher). The theoretical formulation is based on a scheme that describes scattering in systems containing small numbers of nucleons. The numerical realization and an internal check of convergence with respect to higher order terms will also be undertaken. The results of the collaboration should provide interesting insights into the reaction mechanism or light nuclei collisions and lay firm ground to test various physical assumptions, such as the application of free nucleon-nucleon forces in these reactions and the properties of ground- state wave functions of light nuclei.
