Using electron energy-loss spectroscopy (EELS) and many-electron atomic spectral calculations, we examine the O{sub 4,5} (5d {yields} 5f) edge structure of the ground-state {alpha} phase of Th, U, Np, Pu, Am, and Cm metal. Results show that the dipole-allowed transitions are contained within the giant resonance and that the small pre-peak in the actinide 5d {yields} 5f transition should not be labeled the O{sub 5} peak, but rather the {Delta}S=1 peak. Lastly, we present for the first time the O{sub 4,5} EELS spectra for Np, Am, and Cm metal.
