Joint effort in the search for new physics
As part of an international collaboration MPIK researchers carried out highly precise measurements as well as calculations on atomic transitions in calcium isotopes. The results set new limits on a hypothetical particle mediating a force between neutrons and electrons.

Listening to electrons talk: g-factor measurement of lithium-like tin
Researchers from the MPIK present new experimental and theoretical results for the bound electron g-factor in lithium-like tin which has a much higher nuclear charge than any previous measurement. The experimental accuracy reached a level of 0.5 parts per billion. Using an enhanced interelectronic QED method, the theoretical prediction for the g-factor reached a precision of 6 parts per billion.
