Excited States in¹⁸Ne Studied via¹⁷F +p

The elastic resonance scattering of F-17+p is studied in inverse kinematics via a thick-target method. The excitation function for F-17+P elastic scattering is obtained within the energy interval of E-c.m. approximate to 0.4-1.7 MeV. The experimental excitation function is analyzed with a multilevel R-matrix code MULTI7, and the proton widths are deduced. The alpha decay from 6.15 MeV 1(-) state in Ne-18 is observed, which is critical to the O-14(alpha, p)F-17 reaction as the main breakout route from CNO cycle to rp-process in supernovae and x-ray bursts.
