Neutron capture γ-rays from cobalt have been used to photoexcite nuclear levels in the 5-8 MeV region. The decay properties of the 7491 keV level in 55Mn and the 6877 keV level in 142Nd were studied in detail. Total and partial radiative widths of nuclear levels in several isotopes were determined using nuclear self-absorption, temperature variation, and absolute scattering cross section measurements. The total radiative widths were found to be of the same magnitude as those of unbound levels populated in neutron resonances. The spins and parities of some resonance levels were determined by carrying out angular distribution and polarization measurements, respectively.
