Description

Single charged atomic or molecular ions can be confined in ion traps for extremely long times in a well-controlled environment. This provides the conditions for measurements of very high precision. For example Prof. Werth will quote the most recent results from his laboratory: A new determination of the proton´s mass as well as of the magnetic moment of proton and antiproton. Furthermore, he will present measurements of the electron´s magnetic moment when bound in hydrogen-like ions from which a new value of the electron´s mass can be derived.

 

Prof. Dr. Günter Werth is currently professor emeritus at Johannes Gutenberg University Mainz. His areas of research include atomic physics and quantum optics, in particular, the study of fundamental properties of ions and quantum electrodynamics tests using Paul and Penning traps. For his postdoctoral position, he worked in the Goddard Space Flight Center of NASA in 1972/1973. In 1985 he received the Helmholtz Prize for Precision Measurements.
