Gamma-ray strength function measurements for 59Co, 61Cu and 62Cu

Abstract The (p, γ) reaction on 58 Fe, 60 Ni, and 61 Ni has been used to study the radiative E1 strength in the 6–10 MeV energy region. Significant deviations from the lorentzian extrapolations have been found both in shape and absolute values of the strength functions.
