Relativistic dipole selection rules for direct interband transitions in fcc and bcc lattices are derived. High-resolution angle-resolved photoemission spectra of Ag demonstrate that these selection rules are essential for a consistent interpretation of photoemission data even for energy bands which are not split by spin-orbit interaction.
