Unbound states in Ne-28 and F-25 were populated in the reaction of a 102 MeV/nucleon Na-29 beam on a beryllium target. The measured decay energy of 32(22) keV in the Ne-27+n system corresponds to an unbound excited state in Ne-28 at 3.86(11) MeV. This is the first measured unbound state of Ne-28. The decay energy of the F-24+n system was measured as 300(170) keV. This places the second measured unbound state of F-25 at 4.66(17) MeV.
