Spectroscopy of neutron-rich Fe isotopes populated in the 70Zn+238U reaction

Abstract

The excited states of neutron-rich Fe isotopes have been studied through a multinucleon transfer reaction of a 70Zn beam on a 238U target. Unambiguous identification of prompt γ rays belonging to each nucleus was performed by coincidence detection of the ions in a high-acceptance magnetic spectrometer. The observed spectra are compared with large-scale shell-model calculations in the fpgd model space.
