Correlations in Compound-Nucleus Decay Amplitudes in the Vicinity of Isobaric Analog States

Polarization and ($p, p^{\prime }\gamma$) angular-correlation studies near isobaric analog resonances in proton scattering from ${}_{}{}^{92}{}_{}{}^{}\mathrm{Mo}$ and ${}_{}{}^{106}{}_{}{}^{}\mathrm{Cd}$ indicate strong correlations between compound-nuclear decay channels. A modified Hauser-Feshbach formula which includes correlations among these channels which belong to the analog resonance can explain the data.
