Investigation of the 14O(α,p)17F stellar reaction via resonant elastic scattering of 17F+p

Resonant properties in Ne-18 relevant to the stellar reaction of O-14(alpha, p)F-17 have been investigated through a resonant elastic scattering of F-17+p. The F-17 RI beam was produced via a projectile-fragmentation reaction, and subsequently separated and purified by a Radioactive Ion beam Line in Lanzhou (RIBLL). After a series of energy degradation, a 4.21 AMeV F-17 beam bombarded a thick (CH2)(n) target at T2 terminal. Energy and angle of the recoiled protons were measured by two sets of Delta E-E silicon telescope at theta(lab) approximate to 0 degrees, 14 degrees respectively. Several resonances in Ne-18 were observed, and their resonant parameters including energy, spin-parity and decay width have been determined by an R-Matrix analysis of the experimental excitation function.
