Selective Population of Unbound Positive Parity States in $^{\mathrm{25}}$F and $^{\mathrm{26}}$F

Unbound Positive Parity States in $^{\mathrm{25}}$F and $^{\mathrm{26}}$F were populated in the one-proton removal reaction from a radioactive $^{\mathrm{27}}$Ne beam. The experiment was performed at the National Superconducting Cyclotron Laboratory (NSCL), where a 101.3 MeV/u $^{\mathrm{27}}$Ne ion beam impinged on a liquid deuterium target populating states in $^{\mathrm{26}}$F. States above the one- and two- neutron separation energies lead to $^{\mathrm{24}}$F and $^{\mathrm{25}}$F, respectively. The MoNA/LISA setup at NSCL was used to detect the fragments in coincidence with neutrons and the decay energy spectra of $^{\mathrm{25}}$F and $^{\mathrm{26}}$F were reconstructed by invariant mass spectroscopy. Resonance energies of approximately 0.35 MeV~ and 0.5 MeV for $^{\mathrm{25}}$F* and $^{\mathrm{26}}$F*, respectively, were extracted. Based on the calculated spectroscopic strength distribution of negative and positive parity states in $^{\mathrm{26}}$F and the selectivity of one proton-removal reactions both states were assigned positive parity.
