This beam has been used to study the level structure of F at low energies via the p( 15 O,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 are reported. Good agreement with the theoretical spectroscopic factors is also obtained. Electronic address : dwlee@lbl.gov Present address : Radiation and Nuclear Safety Authority, Helsinki, Finland
