Direct-transition analysis of new photoemission data for palladium

The Gilat-Raubenheimer integration procedure has been generalized to the calculation of photoemission energy distributions arising from direct interband transitions. A detailed application to Pd successfully explains the main features of new photoemission data (d-band structure at 0.15, 1.2, 2.2 and 3.5 eV below the Fermi level), thus suggesting that nondirect transitions need not be invoked. © 1970.
