Abstract
The interpretation of the first backbending point in deformed rare earth nuclei as a crossing of the ground state band with a rotational band built on an aligned i 13 2 neutron pair is rather well established. However, in terms of such a two-band mixing model one cannot understand the exclusive population of yrast states in and above the backbending point observed in Coulomb excitation experiments of neutron-rich, stable rare earth nuclei. To investigate this problem in more detail for the heavy Dy nuclei 160, 162Dy, an Incomplete Fusion experiment has been performed at the MPI für Kernphysik in Heidelberg in order to investigate its suitability for studying these n-rich nuclei. A cross section of σ ≈ 150 mbarn for producing the nuclei with a spin distribution covering the first backbending region could be established.
