Titel: Search for a Nuclear Electric Dipole Moment of Radium-225


Permanent electric dipole moments (EDMs) in atoms or molecules are signatures of time (T)- and parity (P)-violation. Experimental searches for these EDMs represent an excellent window to physics beyond the standard model. In the nuclear sector, the best limits for EDMs are currently set by measurements on the neutron and the diamagnetic atom 199Hg. A promising avenue for extending these searches is to take advantage of the large enhancement in the atomic EDM predicted for heavy octupole-deformed nuclei, as can be found in the radium and radon isotopic chains. We are developing a next generation EDM search around laser-cooled and trapped 225Ra. I will give an update on our recent experimental progress towards a first EDM measurement.

Titel: Mass measurements of halo nuclei using the TITAN Penning trap


Precise atomic mass determination plays an important role in various fields of physics. Recently, the TITAN Penning trap measured the mass of several halo nuclei. These exotic systems are composed of a core surrounded by loosely bound neutron(s), forming an extendend neutron veil. In this presentation, we show the newly determined masses of the halos He-6,8 as well as the systematic studies of the TITAN Penning trap.
