The position the neutron 2d5/2 orbital is a crucial benchmark for calculations in the N=40 region using large valence neutron space. In order to improve their predictive power, these calculation models must be constrained using experimental data giving the precise position of this level. Therefore the transfer reaction 68Ni(d,p)69Ni, feeding this level, was produced and measured in inverse kinematics at GANIL. The beam of radioactive 68Ni, delivered on a thin CD2 target, was produced at 25.16 MeV per nucleon in the LISE spectrometer.
The experimental setup consisted of two beam tracking CATS detectors enabling the reconstruction of the position of the reaction's location on target,
four MUST2 telescopes identifying protons at backward angles and giving their energies and positions, and a plastic detector coupled to an ionization chamber in order to identify the 69Ni downstream
. Preliminary results of analysis are shown.
