Multi-Nucleon Transfer Experiments in the Actinide Region — •Kerstin Geibel¹, Peter Reiter¹, Jose Javier Valiente-Dobon², Francesco Recchia², Benedikt Birkenbach¹, Andres Gadea⁴, and Silvia Lenzi³ — ¹Institut für Kernphysik, Universität zu Köln, Deutschland — ²Istituto Nazionale di Fisica Nucleare, Laboratori Nazionali di Legnaro, Italy — ³Dipartimento di Fisica, University of Padova, Italy — ⁴IFIC, CSIC-Universidad de Valencia, Spain

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.
