Abstract
A theoretical discrepancy concerning band crossings at two points along the Λ direction in Pt is clarified by experimental symmetry analysis of the band characteristics, using circularly polarized synchrotron radiation and spin analysis of the photoelectrons by a new low-energy-diffraction analyzer system. Each of the theoretical results is found to be correct at one k point and incorrect at the other one.Keywords
