U.S.-Switzerland Cooperative Research: Calculation of the Relativistic Ionization Form Factor Using Numerical Atomic Continuum Wavefunctions

9214087 Perger这个奖项支持教授沃伦F。密歇根理工大学的Perger与瑞士巴塞尔大学理论物理研究所的Dirk Trautmann教授合作进行物理学研究。 他们联合研究的目标是精确计算相对论电离形状因子。 他们的研究计划有效地利用了他们互补的专业知识。 他们将使用巴塞尔实验小组产生的数据，测试Trautmann教授开发的计算机程序，并使用Beers教授编写的程序生成的原子连续波函数。 这将使比尔斯教授在将他的计算专业知识应用于现实的原子物理问题方面获得宝贵的经验。 相对论效应对电离截面的影响的本质还没有得到很好的理解。 电离截面的详细知识，这可以从电离的形状因子，是非常重要的许多应用原子碰撞理论的等离子体物理和恒星大气物理的研究。 ***

9214087 Perger This award supports Professor Warren F. Perger of Michigan Technological University for collaborative research in physics with Professor Dirk Trautmann of the Institute of Theoretical Physics of the University of Basel, Switzerland. The objective of their joint research is to accurately calculate the relativistic ionization form factor. Their research plan effectively exploits their complementary expertise. They will work with data produced by the experimental group at Basel, testing a computer program developed by Professor Trautmann, and using atomic continuum wave functions generated by a program written by Professor Beers. This will give Professor Beers valuable experience in applying his computational expertise to a realistic atomic physics problem. The nature of relativistic effects on ionization cross-sections is not well understood. Detailed knowledge of the ionization cross section, which can be obtained from the ionization form factor, is of great importance in many applications of atomic collision theory to plasma physics and in studies of the physics of stellar atmospheres. ***
