Abstract:The level scheme of the N=82 nucleus 145Eu has been extended to I=(55/2) and Ex=11.2 MeV in an experiment with the Tessa Compton-suppressed Ge detector array using the 127I(22Ne,4n) reaction. Most of the complicated and irregular level scheme of 145Eu can be interpreted as proton multi-quasiparticle states in comparison to the 64 146 Gd82 core nucleus but also excitations across the neutron N=82 core have been observed.
