Abstract
The combination of high energy and angle resolution (100 meV, ±3°) with spin analysis in photoemission spectroscopy is shown to allow the direct observation of magnetically spin-split electronic states. This is demonstrated for normal emission from Ni(110) with polarized Ne i radiation ( eV). It is found that eV for the exchange splitting of the band at the point in good agreement with a band-structure and photoemission calculation that considers the self-energy correction explicitly.
