U.S.-Hungary Physics Research on N-Body Scattering Theory

这项关于“n -体散射理论”的美国-匈牙利研究项目由dr。新墨西哥大学的Colston Chandler和Archie G. Gibson，以及匈牙利科学院核与粒子物理研究所的Gyula benze博士。研究人员将继续研究库仑相互作用，这是理论物理学中一个困难的、少体的问题，没有实际的、数学上严谨的理论。工作将强调代码开发，以准确地处理库仑相互作用，以数值计算质子-氘核散射的散射振幅。研究人员将继续研究散射理论，以更准确地解释原子分裂反应中的电子相关性。最后，他们将研究具有排斥性库仑相互作用的三个粒子的库仑反应，以确定如何将一个实用的畸变波近似纳入散射理论中。在散射计算中包含破碎通道是目前原子物理和核物理学界非常感兴趣的一个课题。研究人员还打算在钱德勒-吉布森方程的背景下继续他们关于破裂振幅的理论和数值工作。要解决的具体问题是中子-氘核散射的简化模型，尽管这些技术应该适用于更一般的问题。研究还将开始开发一个实用的n体畸变波近似三簇分解波函数。任何一项拟议研究的成功都将在原子或核物理学或两者中具有相当大的实际应用。该理论物理项目通过使匈牙利和美国的领先专家在共同感兴趣和能力强的领域结合互补人才和汇集资源，实现了推进科学知识的计划目标。

This US-Hungary research project on "N-Body Scattering Theory" is between Drs. Colston Chandler and Archie G. Gibson of the University of New Mexico and Dr. Gyula Bencze of the Research Institute for Nuclear & Particle Physics, Hungarian Academy of Sciences. The researchers will continue examination of the Coulomb interaction, a difficult, few-body problem in theoretical physics for which no practical, mathematically rigorous theory exists. Work will emphasize code development to evaluate scattering amplitudes numerically for proton- deuteron scattering, treating the Coulomb interaction exactly. The researchers will pursue work on a scattering theory to more accurately account for electron correlations in atomic breakup reactions. Finally, they will study the Coulomb reaction for three particles interacting with repulsive Coulomb interactions to determine how to incorporate into the scattering theory a practical distorted wave approximation for breakup wave functions. The inclusion of breakup channels in scattering calculations is a topic of considerable interest at present in both atomic and nuclear physics. The researchers also intend to continue their theoretical and numerical work on breakup amplitudes in the context of the Chandler-Gibson equations. The specific problem to be addressed is a simplified model for neutron-deuteron scattering, though the techniques should be applicable to more general problems. Study will also be initiated to develop a practical N-body distorted wave approximation for three-cluster breakup wave functions. Success in any of the proposed studies would have considerable practical application in atomic or nuclear physics, or both. This project in theoretical physics fulfills the program objective of advancing scientific knowledge by enabling leading experts in Hungary and the United States to combine complementary talents and pool resources in areas of strong mutual interest and competence.
