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.

这个项目有四个目标：(1)测量氢原子的里德伯常数，精度达到10.10的1分之一；(2)测定氦原子的电离势至10.9的1 / 2；(3)将分子分析应用于重离子碰撞中产生的电子-正电子和光子对的尖峰；(4)研究压缩辐射场对原子跃迁的影响。我们建议Rydberg常数可以作为一个独特的波长/频率标准，它可以服务于整个频谱。对氦的测量将检验其理论的最新进展，包括相对论效应和兰姆位移。
