212Po lies just two protons and two neutrons above the doubly magic nucleus 208Pb. However, its structure exhibits interesting features of shell model and cluster model configurations [ Ref: A. Astier, Phys. Rev. Lett. 104, 042701 (2010) ]. In April 2016 an experiment was performed at the IKP at the University of Cologne with the goal to determine the lifetime of the 41+ → 21+ transition in 212Po. The HORUS setup, equiped with 8 HPGe and 8 LaBr3(Ce) detectors, was used. The nucleus was populated via the 208Pb(12C,8Be) reaction at 62 MeV. The data were analysed applying the Generalized Centroid Difference Method (GCD) [ Ref: J.-M. Régis et al., Nuclear Instruments and Methods in Physics Research A 726 (2013) 191-202 ]. The status of the analysis will be presented.
