ResumoThe ($p, \ensuremath{\gamma}$) reaction populating highly excited states in $^{28}\mathrm{Si}$ is shown to be dominated by giant dipole resonances built upon one-particle, one-hole states. Each giant resonance is centered at ${E}_{\ensuremath{\gamma}}\ensuremath{\approx}20$ MeV, with a width which increases with the energy of the one-particle, one-hole state, and with a strength that is simply related to the proton stripping strength to the same final state.
