Measurement of the electric dipole moment of the isotope 129Xe
Here we are trying to measure an EDM with the isotope 129Xe based on a dual-species spin clock together with 3He. The experiment is part of an international collaboration, our first results are the currently leading upper limits for the isotope 129Xe, they can be found here:

Among the experimental facilities established for experiments with polarized noble gases, we have set up a lab for hyperpolarization of 3He and 129Xe, using Spin-Exchange Optical Pumping (SEOP). The technique enables us to prepare > 10% spin polarized gas samples for various purposes.
