The neutron-rich Fe isotopes from A=61 to 66 were studied through multinucleon transfer reactions by bombarding a $^{238}$U target with a 400 MeV $^{64}$Ni beam. Unambiguous identification of prompt $\gamma$ rays belonging to each nucleus was achieved using coincidence relationships with the ions detected in a high-acceptance magnetic spectrometer. The new data extend our knowledge of the level structure of Fe isotopes, which is discussed in terms of the systematics of the region and compared with large-scale shell-model calculations.
