High-resolution measurements of analogue states in 59,61,63Cu

Differential cross sections were measured at four angles for proton scattering on ^58,60,62Ni at energies from 3.0 to 4.0 MeV by means of a high-resolution beam from the Tokyo Institute of Technology 4 MV Van de Graaff. An overall resolution of 400 eV was realized using thin solid targets. Five fragmented p-wave analogue states and two fragmented g-wave analogue states were identified in the elastic scattering data. Spectroscopic factors and Coulomb energy differences were extracted for the analogue states. Spins, parities, total and partial widths were obtained for all resonances observed. The s-wave width and spacing distributions were also analyzed.
