“…3 shows there is a pronounced Cooper minimum for the d-f channel at around 220 eV photon energy. 28,29 In addition one finds a less pronounced minimum at 480 eV with corresponding maxima at about 350 and 650 eV. The position of the minima correlate quite well with the centers of the 7f-and 9f-canonical bands of Au, that are derived from the logarithmic derivative of the radial wave functions.…”

Results of a combined experimental and theoretical investigation on the Fano-effect in the angle-integrated valence band photoemission of the noble metals are presented. In line with the fact that the Fano-effect is caused by the spin-orbit-coupling, the observed spin polarization of the photocurrent was found to be the more pronounced the higher the atomic number of the element investigated. The ratio of the normalized spin difference curves, however, agreed only for Cu and Ag with the ratio of the corresponding spin-orbit coupling strength parameters. The deviation from this expected behavior in the case of Au could be explained by the properties of individual d-p-and d-f-contributions to the total spin difference curves, that were found to be quite different for Au compared to Cu and Ag.

“…Initialstate hybridization also affects the magnitude of the Cooper minimum. 17,38,39 If, as is suggested by theory, the Pd 4d and Mn 3d states form a strongly hybridized, delocalized band, then the depth of the Cooper minimum may be significantly reduced from that of the atomic case due to a reduction in 4d character. Such changes have been shown to produce orders of magnitude differences in the Cooper minimum.…”

“…This will not necessarily be the case since the Pd 4d states form a band and solid-state effects may be important. 17,38,39 It is known that bonding and antibonding states in Pd metal exhibit differences in photon-dependent emission intensity, particularly at the Cooper minimum. 17 If this is also the case for Pd alloys such as Pd 2 MnSn, then the antibonding states close to E F may exhibit a more pronounced atomiclike Cooper minimum than bonding states well below E F .…”

“…C(h) includes factors to account for the photon flux, escape depth, detector efficiency, and reflection and refraction of the photon beam at the sample. 17,18 Assuming that variations in escape depth and detection efficiency with electron kinetic energy are not significant across the valence band at a given excitation energy, then this can be considered constant. It will not, therefore, affect the shape of the valence-band spectrum.…”

“…We note that in this photon-energy range, the Au and Pt 5d states of AuAl 2 and PtGa 2 , respectively, show atomic-like behavior, which is in sharp contrast to the solid-state effect observed for the Au and Pt 5d states in Au and Pt metals. 21,22 …”

Synchrotron-radiation-excited angle-resolved photoemission spectra for the (100) and (111) faces of AuAl2 and the (111) face of PtGa2 are presented, along with derived experimental dispersion relations. These bands are compared with those obtained from the first-principles theoretical band-structure calculations. The total densities of states at the Fermi energy for these two materials are compared with those obtained from the specific-heat measurements. The energy variations of Au and Pt 5d bands for AuAl2 and PtGa2, respectively, show atomic-like behavior in the photon-energy range of 80-220 eV.
