The proton energy spectra for the reaction ^<58>Ni(n,p) ^<58>Co at E_n=14.8 MeV show two strong peaks at E_p=11.5 and 14.5 MeV at forward angles. The experimental data on these peaks are analyzed by assuming that they correspond to the direct (n,p) reactions leading to the parent analogue states P of the E1 and M1 giant resonance states C of ^<58>Ni. The parent analogue states P are obtained by using the relation |P> ∝T_+|C> from the E1 and M1 giant resonance states C, which are treated in the particle-hole framework. Calculations are performed for the Q values and for the differential cross sections for the (n,p) reactions leading to these parent analogue states. The theoretical results are in good agreement with the experimental data on the peaks in the proton spectra. The strengths of the isospin and spinisospin dependent parts of the effective two-body interaction between the incident and target nucleons are adjusted to yield the observed cross sections, and their values determined are consistent with those deduced from other experimental data.
