RUI: Indirect Calculation of Lamb Shifts in Three-Electron Atoms (Physics)

建议研究的目的是（i）获得一个 非相对论基态的精确值 能量Li I;（ii）计算相对论贡献 Li I的基态能量;（iii）将结果联合收割机 （i）和（ii）的绝对基态兰姆位移 （四）计算李某的其他成员; 等电子系列，以确定Z依赖的行为， 基态兰姆位移;和（v）将研究扩展到激发态 状态，以确定Lamb移位对各种 光谱跃迁 拟议中的研究将涉及所有大学生 除了一项工作之外， 这些学生将被暴露在 从化学，物理，计算机 科学和数学。 这些学生学到的技能， 例如实用计算机编程，数值分析， 最优化理论，以及攻击和 解决一个研究问题，提供一个重要的资产， 研究生学习。

The objectives of the proposed research are (i) to obtain an extremely accurate value for the non-relativistic ground-state energy of Li I; (ii) to calculate the relativistic contributions to the ground state energy of Li I; (iii) to combine the results of (i) and (ii) to obtain the absolute ground state Lamb shift for Li I; (iv) to calculate other members of the Li I isoelectronic series to determine the Z-dependent behavior of the ground state Lamb shift; and (v) to extend the study to excited states so as to determine the Lamb shift contribution to various spectral transitions. The proposed research will involve undergraduates in all sections of the work except one. These students will be exposed to ideas from the four areas of chemistry, physics, computer science, and mathematics. The skills these students pick up, such as practical computer programming, numerical analysis, optimization theory, and the general mechanics of attacking and solving a research problem, provide an important asset for postgraduate studies.
