Abstract

Electromagnetic transitions in F22 were investigated using the Be9(C14, p) reaction at Elab=22 MeV. Proton-γ and proton-γ-γ coincidences were measured using a segmented E-ΔE Si telescope and the Florida State University γ detector array. γ-ray energies, intensities, and branching ratios were measured, and mean lifetimes were inferred using the Doppler-shift attenuation method. Several new states and many new γ-decay branches were observed. The results are compared with sd shell model calculations using the USD, USDA, and USDB interactions. The excitation energies of the states below 2 MeV agree slightly better with the calculations using the USD interaction, while the levels between 2 and 4 MeV agree somewhat better with those using the newer USDA and USDB interactions.
