Abstract
We show first results and systematic investigations of a matter wave interf erometer with the K-2 molecule, using a transition between the electronic g round state X (1)Sigma (+)(g) and the state b (3)Pi>(*) over bar * (0(u)(+) ). This spin forbidden transition is observable due to spin-orbit coupling between the states b and A (1)Sigma (+)(u). The experimental results are co mpared with numerical simulations, which show the power of the interferomet er to observe small phase shifts by weak interactions.
