Our group members Sven Sturm and Anke Wagner and division director Klaus Blaum are receiving
the Helmholtz Prize 2012 
for precision measurements,
which is the most distinguished German award in the field of metrology.
The three prize-winners are awarded for their high-precision measurement of the g-factor of the
remaining bound electron in a single hydrogen-like silicon ion (28Si13+) by using a
triple Penning trap system. The comparison of the new measured g-factor with the value based on
theoretical calculations represents to date the most accurate test of bound-state QED calculations
in strong fields. The theoretical and experimental value of the g-factor are in excellent agreement.
The experimental work of the awarded researchers thus is an important contribution to a deeper
understanding of the fundamental forces in the universe.
