Cg. Olson et al., CRYSTAL MOMENTUM CONSERVATION IN RESONANT PHOTOELECTRON EMISSION, Journal of electron spectroscopy and related phenomena, 93(1-3), 1998, pp. 175-180
Angle-resolved photoemission spectra taken at the rare earth 4d resona
nce show crystal momentum conservation in emission from 5d states in L
aSb and 4f derived states in Ce2Sb. In both cases the emission resulti
ng from resonant enhancement is shown to be direct photoemission. (C)
