%X Energy distributions of photoprotons emitted at 900 to the bombarding X-ray beam of the Melbourne 35 MeV betatron from thin targets of natural aluminium, sulphur, and silicon, measured with a scintillation spectrometer incorporating pulse-shape discrimination (PSD), are presented. The 27AI proton spectrum, whose shape is found to be inconsistent with predominant evaporation of particles from a compound nucleus, exhibits a "hump" at 8·6 MeV, which is attributed to transitions between known levels in target and residual nuclei.
