Amplitude and width correlations in 57Co and 49V

Angular distributions of the inelastically scattered protons and of the deexcitation γ-rays in the 56Fe(p,p'γ) reaction were measured for d-wave resonances in the proton energy range 3.10 to 4.01 MeV. The experiment was performed with an overall energy resolution of 350 to 400 eV (FWHM) at the Triangle Universities Nuclear Laboratory KN Van de Graaff accelerator and associated high resolution system. Results were obtained for 141 resonances; 83 resonances were assigned J/sup π/ = 5/2+, while 58 resonances were assigned J/sup π/ = 3/2+. Mixing parameters for the inelastic decay amplitudes were uniquely determined for the 5/2+ resonances. The angular distributions for the deexcitation γ-rays were measured in coincidence with the inelastically scattered protons for 30 3/2+ resonances in 49V in the proton energy region 2.2 to 3.1 MeV. Statistical analyses were performed on the set of 83 5/2+ resonances in 57Co and on the set of 30 3/2+ resonances in 49V. In both cases, large amplitude and width correlations are observed. These results are interpreted as evidence for direct reactions between the inelastic channels
