Description: This award is for support of a collaborative research project between Dr. F. Bary Malik, Professor of Physics at Southern Illinois University and Dr. Arun Kumar Basak of the Physics Department at Rajshahi University in Rajshahi, Bangladesh. The proposed work is for theoretical studies of alpha particle-nucleus interaction (for light target nuclei) in the low-to-medium energy regime. The aim is to determine alpha-nuclus interaction for medium-light nuclei from the analyses of elastic, inelastic and particle transfer data and from an inverse scattering theory. The large enhancement of cross sections at back angles in the noted reaction has, in many cases, remained unexplained. The plan is: (1) to expand the functional form of interaction to include both monotonic and non-monotonic functions (or molecular potential) and emphasize surface absorption, (2) to incorporate channel coupling using both types of potential, (3) to allow for actual resonance terms in scattering amplitude, if necessary, and (4) to determine the potential from an inverse scattering theory, particularly if the phase shift analyses are available. Scope: This project will support collaboration between two teams with complementary capabilities and institutional facilities. The US P.I. is well-respected researcher with a long publication record. The foreign collaborator has done significant work in the past. The topic of this research is important, with potential for significant contributions to nuclear reaction theory and should help clear some longstanding issues. The collaboration will have major impact on the ability of the Bangladeshi institute to do this important research and to have access to results from international research. It will also help the US scientist accelerate his research work by having the excellent scientific talent available at the foreign institute. The project fits within the objectives of the Division of International Programs.

描述：这个奖项是为了支持一个合作研究项目，博士F。南伊利诺伊大学物理学教授巴里·马利克和孟加拉国拉杰沙希的拉杰沙希大学物理系的阿伦·库马尔·巴萨克博士。 建议的工作是理论研究的α粒子核相互作用（轻靶核）在低到中能区。 目的是确定α-nuclus相互作用的中轻核的弹性，非弹性和粒子传输数据的分析和从逆散射理论。 在所述反应中，在后角处横截面的大幅增强在许多情况下仍然无法解释。 该计划是：（1）将相互作用的函数形式扩展到包括单调和非单调函数（或分子势）并强调表面吸收，（2）结合使用两种类型的势的通道耦合，（3）如果需要，允许散射振幅中的实际共振项，以及（4）从逆散射理论确定势，特别是如果相移分析是可用的。 范围：本项目将支持两个具有互补能力和机构设施的小组之间的合作。 美国PI是一位备受尊敬的研究人员，有着长期的出版记录。 这位外国合作者在过去做了大量工作。 这项研究的主题很重要，有可能对核反应理论做出重大贡献，并有助于澄清一些长期存在的问题。 此次合作将对孟加拉国研究所开展这项重要研究并获取国际研究成果的能力产生重大影响。 它还将帮助美国科学家通过拥有外国研究所的优秀科学人才来加速他的研究工作。 该项目符合国际方案司的目标。
