Fine structure of analogue states in 55Co, 57Co and 59Co
Abstract
Differential cross sections were measured at four angles for proton elastic scattering from 54, 56, 58Fe at energies ranging between 1.8 and 3.3 MeV. Using the TUNL 3 MV Van de Graaff accelerator and high-resolution analyser-homogenizer system, a total resolution of 300-400 eV was achieved for thin solid targets of enriched iron isotopes. Seven analogue states in 55Co and 57Co appeared as single resonances; three analogue states in 59Co showed well-developed fine-structure distributions. Spin, parities and widths were determined for approximately 200 resonances. Spectroscopic factors and Coulomb energy differences were extracted for the analogue states.
