摘要：
The photoelectron spin polarization from ferromagnetic Ni has been calculated using a combined interpolation scheme. The band structure was adjusted to reproduce the experimental magneton number and the correct EF-L2 separation as determined from recent angle-resolved photoemission experiments. Results of calculations are reported for emission from (100) and (111) surfaces and from polycrystalline samples. Major disagreement with experiment for the (100) surface indicates that surface photoemission is dominant near threshold. It is suggested that energy-resolved measurements will be required if bulk and surface emission are to be distinguished. Calculated energy spectra are reported and discussed. © 1979 The American Physical Society.
