Two experiments at the PRISMA-CLARA-Setup at the LNL in Legnaro were analysed focussing on the target-like reaction products in the actinide region after multi-nucleon transfer reactions. Both experiments use 238U as target; a 70Zn-beam with 460 MeV and a 136Xe-beam with 926 MeV were employed. Kinematic correlations between the reaction partners are used to obtain information about the unobserved target-like reaction products by the analysis of the beam-like particles identified with the PRISMA-spectrometer. Clean γ-spectra from neutron-rich actinide nuclei are obtained with the CLARA-array. An extension of the ground state rotational band in 240U and insights in neutron-rich Th-isotopes were achieved. Based on relative cross section distributions for various reaction channels the perspectives and limitations for in-beam γ-spectroscopy with this experimental method in this mass region will be discussed.
