We report on new results from the reaction 54Fe(d,p)55Fe using the Munich Q3D spectrograph. 13 new states have been observed, for 10 states spin values could be established for the first time and spectroscopic factors were determined for 51 states. The results are compared with large scale shell-model calculations using up to 6 particle-hole excitation of the 56Ni core. Consequences for the N = 28 shell stability will be discussed.
In a second experiment the same reaction was performed in inverse kinematics at a beam energy of 2.5 MeV/u. the aim of the experiment was to compare spectroscopic factors obtained in such an experiment with those from normal kinematics experiments. This is relevant in order to establish the reliability of spectroscopic factors in transfer reactions using radioactive ion beams.
