Low-lying resonant states inF16using aO15radioactive ion beam

A 120 MeV O-15 radioactive ion beam with an intensity on target of 4.5x10(4) pps has been developed at the 88-Inch Cyclotron at the Lawrence Berkeley National Laboratory. This beam has been used to study the level structure of F-16 at low energies via the p(O-15, p) reaction using the thick target inverse kinematics method on a polyethylene target. The experimental excitation function was analyzed using R-matrix calculations. Significantly improved values for the level widths of the four low-lying states in F-16 are reported. Good agreement with the theoretical spectroscopic factors is also obtained.
