Overview

Introduction

Antihydrogen production

Antihydrogen spectroscopy

Experiment 'CW-Lyman-alpha'

Spectroscopy of the 1S-2P transition in hydrogen


Level scheme of hydrogen

Hydrogen is a good candidate for precice comparison of theoretical and experimental results: For one electron bound to one proton it is possible to calculate the levels' structure and position to great accuracy.


 
 
 

The fluorescence at Lyman-alpha

With our Lyman-alpha source the 1S-2P transition in hydrogen was measured for the first time with near natural linewidth [1].
