Excited states of neutron-rich Fe isotopes have been studied through a multinucleon transfer reaction of a Zn beam on a U target at the National Laboratories of Legnaro, Italy. The magnetic spectrometer PRISMA was used to identified the isotopes produced in the reaction, and the CLARA array of Clover Ge detectors to detect their gamma rays. The obtained level scheme were compared with new, state-of-the-art large scale shell model calculations. The large model space used in the calculation, which included the 2d orbital, revealed that this orbit is key in order to obtain excellent agreement between the calculations and the experimental data.
