Delta Excitations in Nuclei, US-Jordan Cooperative Research

产品描述：该项目支持爱荷华州州立大学物理系的James Vary博士和约旦安曼应用科学大学物理系的Mahmoud Hasan博士之间的合作。 合作研究将在理论核物理领域处理核中的Delta激发。 具体来说，现实的核子核子和核子三角洲相互作用将被用来绘制极端条件下的核的性质。 对于轻核，将用有效哈密顿量进行精确对角化。 一个Brueckner约束的平均场方法将被用来与有限的核结果的核状态方程。 这项工作包括来自爱荷华州和约旦的两位科学家与T. S. H.李在阿贡国家实验室（ANL）解决了一组Brueckner-Bethe-Brandow有效的NN和ND相互作用在一个现实的单粒子基础。 范围：本项目将允许具有互补专长的两名调查员开展合作活动。 Vary博士是爱荷华州国际理论与应用物理研究所（IITAP）核理论小组的成员。 该小组有两名教师，两名博士后助理和六名研究生。 它与国际空间大学核实验组合作，建立了微观核理论的力量，旨在利用这些力量来解决与核高能反应有关的问题。Vary开发了评估有效核哈密顿量的能力和技术，这将成为该项目的核心内容。 Hasan博士开发了一种主要的约束平均场动态能力和技术，用于评估有效的ND Hamilton。 在教科文组织的赞助下，该研究所将为该项目提供研究支持，并将协助亚利桑那州立大学建立其电子网络和互联网接入。 该项目是一个很好的例子，以满足INT的目标，促进合作，双方的利益。

Description: This project supports cooperation between Dr. James Vary of the Physics Department at Iowa state University and Dr. Mahmoud Hasan of the Physics Department at the Applied Science University in Amman, Jordan. The collaborative research will be in the area of theoretical nuclear physics dealing with Delta excitations in nuclei. Specifically, realistic nucleon-nucleon and nucleon-delta interactions will be used to map out the properties of nuclei under extreme conditions. For light nuclei, exact diagonalization with effective Hamiltonians will be performed. A Brueckner constrained mean field approach will be used to relate finite nuclear results to the nuclear equation of state. The effort encompasses a collaboration involving the two scientists, from Iowa State and from Jordan, and Dr. T.-S. H. Lee at Argonne National Laboratory (ANL) to solve for a set of Brueckner-Bethe-Brandow effective NN and ND interactions in a realistic single particle basis. Scope: This project will allow a cooperative activity between two investigators with complementary expertise. Dr. Vary is a member of the Nuclear Theory Group under the International Institute of Theoretical and applied Physics (IITAP) at Iowa State. The group has two faculty, two postdoctoral associates, and six graduate students. It collaborates with the ISU nuclear experimental group, has established strength in microscopic nuclear theory and aims to use those strength to address issues related to high energy reactions with nuclei. Vary has developed capability and techniques to evaluate effective nuclear Hamiltonians which will form central elements of this project. Dr. Hasan has developed a major constrained mean field dynamic capability and techniques for evaluating effective ND Hamiltonians. The IITAP, with sponsorship from UNESCO, will provide research support for the project and will assist the ASU in building its electronic networks, and in internet access. The project represents a good case of meeting INT objectives in promoting cooperation with benefits to both sides.
