Precision Laser Studies of Basic Atoms and Nuclei

本项目着重于基本原子和原子核的精密激光光谱研究。利用电光技术测量氦原子的2P态的精细结构，以确定精细结构常数α的新的竞争原子物理源。将使用各种光学和激光技术进行额外的实验，以(1)对理论原子物理学中一些最新的计算和技术进行灵敏的测试，(2)测试最近在少体核理论中的计算及其关于核力的基本假设。

This project focuses on precision laser spectroscopic studies of basic atoms and nuclei. The fine structure of the 2P state of the helium atom will be measured with an electro-optic technique in order to determine a newly competitive atomic physics source for the fine structure constant alpha. Additional experiments, using various optical and laser techniques, will be performed to (1) provide sensitive tests of some of the newest calculations and techniques in theoretical atomic physics and (2) test recent calculations in few-body nuclear theory and their underlying assumptions about the nuclear force.
