Abstract
We have used the Empirical Pseudopotential Method to obtain electronic densities of states and charge distributions for the valence electrons in trigonal Se and Te. We have explored the relation between density of states structure and charge density. Specifically, structures in recent photoemission spectra are identified with particular interchain and intrachain bonding states. These results are then used to interpret the changes observed in the experimental photoemission spectra of amorphous Se and Te.
