The analysis of H-1(O-14, p) O-14 and H-1(O-14, 2p) N-13 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 O-14, and by sequential 2p emission to the ground state of N-13 via the 1(-) resonance of O-14. 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 H-1(O-14, p) O-14 and resonance spectrum in F-15 are well reproduced in the unified framework of the GSM.", optnote="WOS:000811520800003", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=5268), last updated on Mon, 04 Jul 2022 07:42:01 +0000", issn="2469-9985", doi="10.1103/PhysRevC.105.L051301", opturl="https://arxiv.org/abs/2111.14412", opturl="https://doi.org/10.1103/PhysRevC.105.L051301", language="English" }
