New narrow resonances observed in the unbound nucleus 15F

The structure of the unbound 15F nucleus is investigated using the inverse kinematics resonant scattering of a radioactive 14O beam impinging on a CH2 target. The analysis of 1H⁡(14O,p)⁢14O and 1H⁡(14O,2⁢p)⁢13N reactions allowed the confirmation of the previously observed narrow 1/2− resonance, near...

Resumo:The structure of the unbound 15F nucleus is investigated using the inverse kinematics resonant scattering of a radioactive 14O beam impinging on a CH2 target. The analysis of 1H⁡(14O,p)⁢14O and 1H⁡(14O,2⁢p)⁢13N reactions allowed the confirmation of the previously observed narrow 1/2− resonance, near the two-proton decay threshold, and the identification of two new narrow 5/2− and 3/2− resonances. The newly observed levels decay by 1p emission to the ground of 14O, and by sequential 2p emission to the ground state of 13N via the 1− resonance of 14O. Gamow shell model (GSM) analysis of the experimental data suggests that the wave functions of the 5/2− and 3/2− resonances may be collectivized by the continuum coupling to nearby 2p- and 1p-decay channels. The observed excitation function 1H⁡(14O,p)⁢14O and resonance spectrum in 15F are well reproduced in the unified framework of the GSM.
