The (p,..gamma..) reaction populating highly excited states in /sup 28/Si is shown to be dominated by giant dipole resonances built upon 1 particle - 1 hole (1p-1h) states. Each giant resonance is centered at E..gamma.. approx. = 20 MeV, with a width which increases with the energy of the 1p-1h state, and with a strength that is simply related to the proton stripping strength to the same final state.
