用自旋极化电子源测量了Ni（110）在9.7eV光子能量下的逆光电子能谱。与能带理论一致，在费米能级上方观察到一个d带衍生峰，该峰对应于仅向少数自旋态的跃迁，并且随着电子入射角的增加，其强度增加并显示轻微的（0.1 eV）能量色散。非弹性背景显示出意想不到的非零（± 5%）偏振。
Inverse photoemission spectra have been measured on Ni (110) at 9.7-eV photon energy with a spin-polarized electron source. Consistent with band theory, a d-band-derived peak is observed just above the Fermi level that corresponds to transitions to minority-spin states only, and which increases in intensity and displays a slight (0.1-eV) energy dispersion as the angle of electron incidence is increased. The inelastic background displays an unexpected nonzero (∼-5%) polarization.
