The {ital L}{sub 3}- to {ital L}{sub 2}-intensity ratios of the valence-band x-ray-emission spectra of 3{ital d} transition metals are corrected for effects of Coster-Kronig transitions. A quantity {ital R}{sub {ital E}} is obtained which is the x-ray-emission analog of the white-line'' {ital L}{sub 3}- to {ital L}{sub 2}-intensity ratio measured in x-ray absorption. The values of {ital R}{sub {ital E}} so obtained do not show evidence for a dependence on magnetic moment that is observed in the corresponding intensity ratios in x-ray absorption. A comparison is made between the values of {ital R}{sub {ital E}} obtained here, and those of a related quantity determined with use of appearance-potential spectroscopy. We find evidence supporting a spin-orbit-splitting model for the {ital L}{sub 3}- to {ital L}{sub 2}-intensity ratio of Ni metal in x-ray absorption.
