Abstract
Second-derivative spectra of photoelectron energy distributions from vacuum-cleaved Te were obtained with polarized light of energy 5.2 to 9 eV. Resolution was between 50 and 100 meV using modulation amplitudes up to 1.0 V. Five main structures arise as a result of transitions from the -valence-band triplets, in good agreement with bandstructure calculations. For the first time -conduction-band minima can be located unambiguously at 5.0, 5.6, and 6.3 eV above the valence-band edge.
