  Radion stabilization is analyzed in 5-dimensional models with branes in the
presence of Gauss-Bonnet interactions. The Goldberger-Wise mechanism is
considered for static and inflating backgrounds. The necessary and sufficient
conditions for stability are given for the static case. The influence of the
Gauss-Bonnet term on the radion mass and the inter-brane distance is analyzed
and illustrated by numerical examples. The interplay between the radion
stabilization and the cosmological constant problem is discussed.
