Description
Experimental searches for permanent electric dipole moments (EDM) on a fundamental particle are predominantly executed in composed systems, such as neutrons, atoms or molecules. The experiments have reached a sensitivity which narrows the gap to the Standard Model predictions significantly which requires an improved understanding of the properties of composed systems in a particular experimental implementation. The NL-eEDM collaboration has built an experiment which employs a molecular beam of barium-monofluoride (BaF) [1]. We will discuss the measurement process of spin-precession in external electric and magnetic fields [2]. The method provides a path to the reduction of a systematic bias to an eEDM, in particular to the applied external electric field.
