Observations of galactic radioactivity by γ-ray telescopes have provided a direct measurement of the 60Fe/26 Al ratio dispersed across the galactic plane. As the two isotopes are thought to be produced in similar stellar environments, the ratio provides a unique constraint on current stellar models. Specifically, 60Fe is expected to be created and destroyed by neutron capture on stable iron isotopes. A recent measurement of the 60Fe(n, γ)61Fe reaction has provided a first experimental quantification of the destruction rate. Currently, no experimental data exist for the 59Fe(n, γ)60Fe production rate. To address this void, a Coulomb dissociation experiment has been performed at GSI in an attempt to indirectly measure the ground state neutron capture cross section of 59Fe. The 60Fe beam was produced by fragmentation of a 660 AMeV primary 64Ni beam by a Be target. The subsequent 60Fe fragments were separated using the FRS and impinged on a lead target. The experimental setup provides for an event-by-event reconstruction of the four-momenta of all incoming particles and reaction products. The analysis is currently ongoing.
