L. Duo et al., A NOVEL SOFT-X-RAY SOURCE (H-NU=151.6EV) FOR CORE-LEVEL AND VALENCE-BAND PHOTOEMISSION SPECTROSCOPY WITH HIGH SURFACE SENSITIVITY, Journal of electron spectroscopy and related phenomena, 62(4), 1993, pp. 309-316
A new soft X-ray source exploiting the Zr Mzeta X-ray transition at hn
u = 151.6 eV is described. This source yields core level and valence b
and photoemission spectroscopy with high sensitivity to the surface an
d to valence s- and p-derived states with respect to the d-derived sta
tes. An in situ cleaning procedure of the anode surface yields a resol
ution of 1.05 eV full width at half maximum.
