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

Resonant properties in ¹⁸Ne relevant to the stellar reaction of ¹⁴O(α,p)¹⁷F have been investigated through a resonant elastic scattering of ¹⁷F+p. The ¹⁷F 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 ¹⁷F beam bombarded a thick (CH₂)_n target at T2 terminal. Energy and angle of the recoiled protons were measured by two sets of ΔE-E silicon telescope at θlab ≈ 0°, 14° respectively. Several resonances in ¹⁸Ne 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.
