High-resolution measurements of analogue states in 55Co

Differential cross sections were measured at four angles for proton elastic and inelastic scattering on ⁵⁴Fe at energies from 3.25 to 4.0 MeV by means of a high-resolution beam. An overall resolution of 400 eV was realized using thin solid targets. Spins, parities and partial widths were extracted for all resonances observed: two p-wave, one f-wave and one g-wave analogue state, all of them being fragmented and identified in the elastic and inelastic data. Spectroscopic factors and Coulomb displacement energies were obtained for these analogue states. The γ-ray angular distributions and resonance strenghts were measured on the $\text{g}{}_{\mathrm{<mtext>9</mtext><mtext>2</mtext>}}$ resonances to determine rates of the IAR-AIAS M1 transition and the El transitions to the low-lying states including the g.s.
