Abstract
The influence of the presence of resonances in a one-dimension-tight-bindin g model is studied. The energy dependence of the density of states and the localization length at different resonance energies and strengths of coupli ng between resonances and random states are determined. The results show, a s a function of energy, a resonance enhancement in the density of states an d a drastic decrease of the localization length except at the resonance ene rgies.
