Description
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 18Ne+p in inverse kinematics. An intense (4 x 106 pps) 18Ne radioactive beam was produced at the Radioactive Beam 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 analysed using the R-matrix method. 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
