AB Two high-lying states in 15F and 16Ne, unbound with respect to one-proton (1p) and two-proton(2p) emissions, have been observed in fragmentation of 17Ne at intermediate energies. They undergomainly sequential emissions of protons via intermediate states in 14O and 15F and have decay energiesof 7.8(2) and 7.6(2) MeV, respectively. The widths of the newly-observed states in 15F and 16Ne aremuch smaller than the Wigner limits for single-particle con¯gurations, of 0.4(4) and 0.8(¡4+8) MeV,respectively. In addition, narrow widths of 0.2(2) MeV are derived for two other high-lying states in15F with Qp of 4.9 and 6.4 MeV, which match features of the recently-predicted narrow odd-parity15F states with two valence protons in the sd shell. All energies and widths have been obtainedby analyzing angular correlations of the decay products, p{p{14O and p{p{13N, whose trajectorieshave been measured by a tracking technique with silicon microstrip detectors.
