Laser Spectroscopy of Basic Atoms (Physics)

本项目有四个目标：（1）测量Rydberg 氢原子常数，精度为1/10.10; (2)来确定氦原子的电离势 （3）将分子分析应用于尖锐的 重离子产生的正负电子和光子对的峰值 （4）研究压缩辐射场对 原子跃迁 这表明里德伯常数可能 用作唯一的波长/频率标准，可 服务于整个频谱。 氦气中的测量 将测试其理论的最新进展，包括相对论 效果和Lamb移位。

This project has four goals: (1) to measure the Rydberg constant in atomic hydrogen to a precision of one part in 10.10; (2) to determine the ionization potential of atomic helium to one in part in 10.9; (3) to apply molecular analysis to the sharp peaks in electron-positron and photon pairs produced in heavy ion collisions; (4) to study effects of a squeezed radiation field on atomic transition. It is suggested that the Rydberg constant may be used as a unique wave length/frequency standard, which can serve throughout the entire spectrum. Measurements in helium will test recent progress in its theory, including relativistic effects and Lamb shifts.
