Welcome to the world of muonic atoms!
I am a research scientist at the Max-Planck-Institute of Quantum Optics in Garching, Germany, and newly appointed Professor at the Johannes Gutenberg-University in Mainz. My main project is laser spectroscopy of exotic "muonic" atoms: muonic hydrogen, deuterium, and muonic helium ions. These experiments take place at the Paul-Scherrer-Institute in Switzerland.
Muonic Deuterium results published in SCIENCE: The deuteron charge radius is also smaller than the CODATA value!
We have previously used the laser spectroscopy of muonic hydrogen to measure the size of the proton. This was the Nature title story on July 8, 2010. More data and a refined analysis were published in Science in Jan. 2013.
Check out the Research pages for more details.
In 2013/14 we have measured the 2S-2P Lamb shift in muonic helium ions. This will allow us to determine the charge radii of the helium-3 and -4 nuclei with ten times better precision.
I and my project "CREMA" receive funding from the European Union's Seventh Framework Programme (FP7/2007-2013) under grant agreement number 279765.
