Ionic, Atomic and Molecular Physics

一台精密质谱仪，足够灵敏，可以检测到单个捕获离子的离子回旋共振频率，将用于测量He/H质量比，提供电子中微子的巢质量上限。它应该可以确定伽马射线的质量，从而确定普朗克常数和阿瓦加德罗常数的乘积，也可以独立确定另一个实验中的精细结构常数，俘获离子技术将用于研究原子之间的碰撞，其能量低于大多数热原子碰撞过程温度的百万分之一。提供对碰撞过程中自发衰变的理解，以及在碰撞过程中使用辐射来切换势曲线

A precision mass spectrometer, sensitive enough to detect the ion cyclotron resonance frequency of a single trapped ion, will be used to measure the He/H mass ratio, providing an upper limit on the nest mass of the electron neutrino. It should be possible to determine the mass of a gamma ray and thence the product of Planck's constant and Avagardro's number, also independently determining the fine structure constant in another experiment trapped ion technology will be used to study collision between atoms at energies below one millionth of the temperature of most thermal atomic collision processes, providing understanding of spontaneous decay during the collisions and the use of radiation to switch potential curves during collision
