The ground state of 28F has been observed as an unbound resonance 220 keV above the ground state of 27F. A comparison of this result with USDA/USDB shell model predictions leads to the conclusion that the 28F ground state is primarily dominated by sd-shell configurations. Here we present a detailed report on the experiment in which the ground state resonance of 28F was first observed. Additionally, we report the first observation of a neutron-unbound excited state in 27F at an excitation energy of 2500(220) keV.
