We have studied the resonant elastic scattering reaction 18Ne+p in reverse kinematics, by using the intense (4 × 106 pps) 18Ne radioactive beam at the Centre de Recherches du Cyclotron RIB facility at Louvain-la-Neuve. The recoil protons were detected at 20 different angles in the LEDA segmented silicon detector. The resulting elastic scattering cross sections have been analysed using the R-matrix method. We have observed for the first time the second excited state (Jπ = 1/2+, ℓ = 0) of the proton-rich nucleus 19Na at the center-of-mass energy Ec.m. = 1.066 ± 0.003 MeV with a proton width Γp = 101 ± 3 keV. The Coulomb shift between the 1/2+ mirror levels in 19O and 19Na is 0.73 MeV, among the largest values currently observed in light exotic nuclei., info:eu-repo/semantics/published, Nuclear physics in astrophysics.

The second excited state (Jπ = 1/2,+, l = 0) of the proton-rich nucleus 19Na has been observed for the first time using the elastic scattering reaction 1H(18Ne, 1H) 18Ne. An intense (4 × 106 pps) 18Ne radioactive beam was produced at the CRC-RIB facility at Louvain-la-Neuve to bombard a polyethylene target. The recoil protons were detected at 20 different angles in the LEDA segmented silicon detector. The resulting elastic scattering cross sections have been analyzed using a global R-matrix. fit. We find that the second excited state in 19Na lies at the center-of-mass energy Ec.m. = 1.066±0.003 MeV with respect to the 18Ne+p threshold, and has a proton width Γp = 101±3 keV. The Coulomb shift between the 1/2+ mirror levels in 19O and 19Na is 0.73 MeV, among the largest values currently observed in light exotic nuclei., info:eu-repo/semantics/published

The second excited state (J(pi)=1/2(+), l=0) of the proton-rich nucleus Na-19 has been observed for the first time using the elastic scattering reaction H-1(Ne-18,H-1)Ne-18. An intense (4x10(6) pps) Ne-18 radioactive beam was produced at the CRC-RIB facility at Louvain-la-Neuve to bombard a polyethylene target. The recoil protons were detected at 20 different angles in the LEDA segmented silicon detector. The resulting elastic scattering cross sections have been analyzed using a global R-matrix fit. We find that the second excited state in Na-19 lies at the center-of-mass energy E-c.m.=1.066+/-0.003 MeV with respect to the Ne-18+p threshold, and has a proton width Gamma(p)=101+/-3 keV. The Coulomb shift between the 1/2(+) mirror levels in O-19 and Na-19 is 0.73 MeV, among the largest values currently observed in light exotic nuclei.
