Proton spin-flip in ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}(p,p_1){}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ ($2^{+}$, 4.44 MeV) has been measured in the region of the 8.9-MeV ${\mathrm{½}}^{-}$ level in ${}_{}{}^{13}{}_{}{}^{}\mathrm{N}$. The inelastic decay is predominately by $f_{\frac{5}{2}}$ waves. The reduced width in the $f_{\frac{5}{2}}$ channel is about equal to the single-particle limit.
